It's my first LT1 job, and if I had known what I was going to run into, probably would have found an older style motor and gone with that. Plenty of oem brackets in my parts bins for the older motors. And that's what I'm used to. It's a done deal now though, time to move on and get the rest of it done!

I do admire that you've fitted so many of these LT1s into so many rigs. I have a '70 Buick Skylark stashed away for a future project, looking at that massive engine bay it looks like plenty of room to stick just about anything I want in there...

No, I haven't forgotten this car, various problems with my '55 4dr gasser, and my two trucks, a '55 Chevy 4x4 and a '58 Chevy pro streeter, and trying to get my '62 panhead chopper I've had for over 40 yrs back on the road, have kept me pretty busy....

Of course you married guys will recognize the "honey-do" list, I do have to put time into that every day....
The '62 panhead if you are interested...

But I will finish that beautiful hardtop....

Had to drop this project for awhile, some health problems, and I managed to break my left arm, kinda slowed me down a bit....

As my arm gets stronger, and feeling better, I'm starting to get back onto the '55 HT project...

Lookin' at why the power steering pump is out of alignment, with this March Performance setup I bought...
The pump sits about 1/8" too far forward....
It sits just below the alternator, and closer to the motor in this pic...


These spacers, 0.316" thick, came with the March Performance LT1
setup, but they are obviously too thick for this particular setup with
these particular heads and block. Everything else seems to fit just fine
now that I have the dampner problems sorted out....

I had a variety of allen head bolt length available to get
a good fit with the proper spacers....

Picked up a dozen ss flat washers, these are 0.050" thick....


Behind the idler rollers and bracket, is the bracket for the PS pump,
that's where the spacers have to go to align the pump....


I started with two washers, 0.100" spacing, wasn't quite right,
added another washer to each location, 0.150" now....


It looks good, don't think I can get it much closer....


These LT1 motors from the mid 90's were a bit of an odd duck, with the ignition (Optispark) mounted directly behind the water pump, and both driven directly off of the cam....

hi don't feel bad. Had same problem on gen 1 350 sbc with the power steering pump.It didn't line up on the march serpentine pulley system neither. Had to machine spacer's to make it work.

It's a slow go, the broken left forearm was in 3 pieces, Doc said a couple more months before it is back "up to speed", but at least I'm able to do a few chores....

Willy, Sorry to hear about the arm and hope it is healing up well. You can milk that for the honey do's for quite awhile if done just right.
I managed to break or rupture the index and middle finger tendons in my left hand a few months ago and have no idea how I did it. Doc said it looked like a crush injury. It has limited how far I can bend the hand with my fist closed. I have been doing the ice/heat and compression combined with stretches for a few months now and have about 80% use back.
Good to hear you are still pushing through though and can't wait to see you in September.
I will have to schedule a trip your way this coming spring.

The broken arm is pretty well healed, but still quite a bit of pain, choosing to just ignore it and trying to get back to work on the Sport Coupe project....

Time to hang the fuel tank and install the fuel system....

Dug out the fuel tank, pump and other parts I've had
in storage for some time now....


Using all Aeromotive parts for an intank efi style fuel pump system...

That hole in the back of this fuel tank is for a fuel gage, any ideas out there for what I should look for in a sending unit that will fit that hole and this tank correctly ??

Finally figured out how it was supposed to fit....

The front mount will fit in nicely with my sway bar frame mounts....

Some slight modification required here....

Another view....

This will be easy....

Gotta cut a 3-1/4" hole for the Aeromotive fuel pump and fuel well....

And will cut and fab a removable piece of the trunk floor over the fuel pump....


More Later....

Does the tank have to sit so low? Can you raise it up a bit? Or does the trunk floor actually sit that low? (I'm only familiar with the wagons, which the floor sits 3 inches (or so) higher than the top of the frame rails).

I got the tank from Earl Williams at Williams Classic Chassis Works in La Verne, CA, they built it specifically to fit my '55 hardtop frame, with a top mounted Aeromotive pump that I'll install. Measured a friend's hardtop, as the body is still off of mine, and it looks like there is not a lot of room under there, maybe 2" max, and the top of the pump sticks up about an inch, so am guessing that it is about where it needs to be. Will find out for sure when I put the body back on.

Got some more work done on the fuel tank....
I trimmed the front support angle to get a better fit on the sway bar frame supports....

If I mount the fuel pump in the front of the tank, left side of the trunk floor is the easiest to cut an access hole for future removal and maintenance....

So I went ahead and cut the required 3-1/4" hole in the front left part of the tank....

Cleaned up and smoothed the rough edges of the new hole....

I propped the tank up so that corner was lowest to keep the mess mostly located right under the hole, and it vacuumed out nicely....

Aeromotive supplied a jig to drill the holes for the new fuel pump....

The idea was to drill two holes opposite each other, then keep it located with these two screws while drilling the rest of the holes...

However, my drill bit went 'south' on the second hole, so I'm going to have to resharpen this bit after each hole, or go buy a couple more bits....
Probably will end up doing both....

More Later...
Aloha,
Willy

Cleaned up the drilled holes for the fuel pump, inside and out....

Used the shop vac to suck out all the debris....

Put the inside ring with the screws in place,,,,
had to file some of the holes to get a good fit....

The nuts are removed after the inside ring is pulled into position...
It is a tight enough fit that it stayed in place....

The front of the tank is 9-1/2" deep (28 gallon tank)...
so the foam is cut to 10-1/2"....
The tank tapers to 9" deep in the rear....

And stuffed down in the tank and massaged back into shape and into position

Then the foam gasket is put on top....

The pump assembly is also assembled to match the 9-1/2" depth...

Had to readjust the foam fuel well a couple of times to get it right....

I think it's good to go....

Now to work up some front mounting brackets....


Aloha,
Willy

What about a sump baffle at the base of the pickup? A sort of tray with sides to keep it full of fuel when cornering?
Do you suppose with your existing setup, that the foam will hold enough fuel for cornering, and not momentarily starve (creating air heading forward to the engine)? Just curious here...

A couple of guys around here have used this setup with good results, that black cup and the foam apparently work pretty well for that, There are four holes on the sides at the bottom of the cup, and I tried hard to follow Aeromotive's instructions to set that cup flat on the floor of the tank, with the bottom 'sock' on the fuel pump intake flat on the floor. By cutting the yellow foam to 10-1/2" tall, and carefully installing it in that 9-1/2" high tank space, I should get the best results. We shall see.

I wanted to put that pump at the rear ofthe tank, but the tank is tapered to the rear and is a half inch deeper in front, so I put it there.
Guess I'll find out....

Rolled the chassis out from under the body,
easier to work on the fuel system....

Loosened up the bolts in back, jacked up the front to cut some more
metal off the front brackets on the tank for a better fit....

While it was up, got in there and ground off paint, cleaned up weld areas....

AND fitted a piece of 3/16 to weld on as a bracket on each side..

Both sides welded on, tacked on while
clamped to the fuel tank to keep then located...

Man, this SS was the toughest stuff to drill I've ever run across....
Using Ace's best bits, I went through 8- 1/4" bits, and 4- 3/8" bits
and that was with a drilling lube and running slow speed, and resharpening
bits with a "Drill Doctor"....

Using cad plated 3/8" bolts, 3/4" long, with flat washers, cad plated, both sides,
a lock washer and a regular nut.

Will pull it out to paint the recent welds,
and I want to coat the welds on this SS tank....

Since I painted the frame with Rustoleum
Black Hammer Tone, decided to do the tank
with the same....

It took two coats plus a little bit here and there, but it looks good to go....

Looking at the tires, and not happy....
They've been in storage for, what, 5 years or more??

The front left tire....
Do you see anything??

Here, I marked it with tape...

A close up....

I sure don't want to drive around on a tire like this....

Had some glaspaks from some past project,
stuck 'em in there to see how they looked...

Have been traveling over the holidays, it sure is nice to get back home and back in the shop....

I need to figure out my fuel system...
I'm not familiar with these early 90's LT-1 efi systems,
Here's what I have to start with....

The motor is built up, 396 ci, ported heads, the plenum has been
port matched to the heads, and the throttle body end
of the plenum has been bored out to match a larger throttle body....

Some stock fuel rails, a 10 micron filter, a pressure regulator....

There's also a box of high flow injectors that are supposed to work with this motor....

The fuel fails match up to the plenum, don't see a problem there....

Here's a complete stock '93 LT-1 Camaro Z28 motor I can pull parts off of if needed....
But I'd rather leave it complete if I can....

Another view....

View #3....

One more....

I need to find instructions on how these systems worked,
and figure out what I need to do with mine....

In the meantime, I'll plumb in the fuel lines....

The Aeromotive fuel pump I mounted in the tank came with AN-6 fittings...

Changed 'em out for AN-8 fittings and put on the hose ends
I want to use to see how well they fit...

That ridge just under the hose ends was a very tight fit...
But I got them on....

Time for some hose....

I think this will work quite nicely....

Had some clamps and some old rubber hose around, so check out the fit...

Yeah, this will work....

Hung the hoses (a feed hose and a return) on the inside
of the right frame rail with clamps about every foot...

Had to route them around the body mount brackets,

Will put some protective hose on the fuel lines anywhere
they might rub on a metal bracket...

I need to pull off the right side header to drill and mount the last two
sets of mounting clamps...

Installing AN-8 fittings and plugs in the pressure regulator...

I had to change out the spring in this regulator,
it came with a low pressure spring for a carb setup,
and I needed the high pressure spring for the efi setup,
but that spring was much shorter then the carb spring,
and that short adjusting bolt was too short to use with
the high pressure spring, so I got two more bolts, the one
in the middle looked the best, so will use it....

Fitting together the fuel and exhaust systems

Had to pull off this right side header to get a drill in
for the last two fuel line mounts....

The header is going to be close...

Yes, I'm going to need some insulation for those fuel lines
to protect them from the exhaust heat

Or, wrap the exhaust system to keep the heat away from the fuel lines...

What are these ports on the rear of the plenum for?

Also on the left side....

And on the right side....

Not sure...but here's a guy selling one from a 93 with a bunch of pics on eBayHere

I think many of those are ports for the various sensors needed for electronic fuel injection setups.

Decided to block off the EGR (Exhaust Gas Recirculation) Ports...
A ball peen hammer and sharp edges make cutting templates easy....

Gotta transfer that to some 1/8" plate....

Get the holes drilled accurately first....

And finish shaping them to fit the templates....

Paint next....

Trying to figure out how to connect these fuel lines on the fuel rails....
The rear tube is 3/8" and I'm told is the fuel in connection...
The front tube is 5/16" and I'm told is the fuel return line...
I've ordered an AN-8 connector for the 3/8" line,
and an AN-6 connector for the 5/16" line.

And a tee with both AN-6 and AN-8 connections for the fuel
return connections at the fuel PR valve...


The upper tube in this pic is the 5/16" fuel return line.
Under the fuel rail it is connected to that black device....
I'm guessing that device connects to engine vacuum??
This one is pretty old and gnarly, think I need to get a new one...


Any Comments?

Thanks for the pix and info guys...

It's been rainy here, humid, it took these block off plates for the EGR openings in the plenum forever to stop being "sticky" so I could install them...


More pix of this fuel return setup at the fuel rail....


I'm trying to find info on exactly what this device is, it looks like a manifold vacuum
operated device to control fuel pressure in the fuel rails....


It's obviously not adjustable, and I'm trying to find out how it operates,
and what the specific parameters are, and if I can just dump it and
plug the hole in the rail? Or find another one that is adjustable so
I can tune it to my particular requirements?
After all my fuel pressure regulator is a constant flow return type, and is mounted right next to the motor, and feeds directly into those fuel rails, so I am trying to figure out just what this device does in addition to my Aeromotive PR, like maybe it adds additional pressure when the manifold vacuum drops??
Hmmmmm.....


These are the fittings I found to attach AN hoses to these fuel lines at the fuel rails....
