I bought this '51 Coupe in 1995. The engine was disassembled, the interior was shot, but overall it was a good solid car that was originally sold in my home town. I don't have a lot of pictures of the early years, but I'll add what I can find.
My sons and I installed a tired 216 engine that we had around and we drove it like that for a few years. After a while, I built a '54 235 ci and installed a 5 speed and S10 rear end on the stock rear springs. I put about 50,000 miles on it in that configuration.

The biggest update came in 2017 when I decided to install a Jaguar front suspension and air conditioning.
That project included completely gutting the interior for new front floor pans and installing sound deadening, front to rear rewiring, new steering column and 66 Impala steering wheel and many, many other "clean up" details.

The first step was to find centerline of the stock front end. I was happy with where the tire was in the wheel well, so no adjustment was necessary.

Then it was time to remove the stock suspension

After doing a lot of measuring, I found that the 1985 Jag front suspension is 2.5" wider than the stock Chevy. I had decided to use the Jag rather than a common aftermarket suspension because I felt it would be more durable. I've seen too many cracked crossmembers and broken and bent components on aftermarket kits. I drive this a lot and don't want any of those issues.

I didn't want to increase the track width so I narrowed the cross member 2.5"

I also narrowed the rack and pinion the same amount so it would keep proper geometry. I also removed the power assist piston so it is now a manual rack.

I fit the cross member to the bottom of the frame to see where the ride height would be. I had cut the coil springs in the stock front suspension and I liked the ride height. I didn't want the car to sit any higher in the front with this suspension.

I located the centerline of the cross member and referenced it from the front of the frame rail.

After measuring the ride height I decided that the cross member would need to be recessed into the frame rails. This would also provide a good welding joint. I notched the frame rails and slipped the crossmember in and welded it solid.

I made these upper shock brackets to accept some short shocks I found. After driving with them, I didn't like them so I had to extend the brackets and put on some longer Bilstein shocks. They work really well.

The '51 was a front mount engine so I had to make side mounts for the '54 block.

Some black paint covers up all the bare metal.
Then it was time to weld up a zillion holes in the firewall. I elected to eliminate the ribs.
I put a dimple in the firewall to gain extra clearance around the Fenton headers I was installing. I ended up changing it some and making it larger and smoother. I'll try and find a picture.

Now I pay the price for moving the cross member up. I need to modify the inner fender panels. And the vent tube, and the heater box. All to gain clearance for the upper A arms.

I flipped the drivers side air tube so there would be more clearance for the a/c compressor that was to come.

While it was torn apart it was time for new front floor pans. The rest of the floor is solid. Only the L and R front needed replaced.

I wanted to add shoulder belts so I made a "bung" to weld into the B pillar. I trimmed the inner skin so it could be welded in flush.

When I cleaned up and painted the vent doors, all of the "horse hair" gaskets had disintegrated. I bought some felt and cut some crescent shapes and worked them into the doors with a couple of screw drivers. It took a while, but they work good now and seal up great.

Thanks for the complements.

I came across this old Tattersfield dual carb intake that I wanted to run. It was originally for a 216, so the port diameter was different than the 848 head I was running. I needed to use the adapter type intake rings, but I also found that the intake was too close to the Fenton headers I was going to run. I needed to space the intake away from the head about 1/4". I decided to machine some spacers that had different diameters on each end to precisely locate the intake to the head. Hopefully the pictures explain it better.

After the intake and Fenton headers were installed, I installed a set of Langdon's progressive 2bbl carbs. I wanted to get away from the rod type throttle linkage and use a cable. I fabricated a bell crank arrangement and modified the linkage I got from Langdon.
I also made new manifold clamps because the stock ones just wouldn't fit right due to the Fentons and the new intake mounting.

In my humble opinion, you have the best intake for your engine. I've found it to be the easiest to tune my carbs with and the runners will allow an unrestricted air fuel flow into the cylinders. They don't look too bad either!!

The intake spacers you made are very good. I have bought insert's to install a 216 intake manifold on a 235 or visa versa. Have 2 sets of them.
