I was running 4:11's in a 12 bolt posi that came out of Thadd's son's '66 El Camino race car that I gad bought from him years ago. I had plans of installing a Gear Vendor OD but plans changed as I am more focused on another project. So I decided to change the gears to 3.55. Well turns out that when up upgraded the axles the shop that did the install not only did they not weld the perches correctly or completely they also failed to discover a bent tube and notice that the rear had been built incorrectly causing the passenger axle to be off by almost 3/16". How this rear lasted this long is simply amazing.
Well now driving it with the new ratio the engine seems to be much happier. It feels almost like the power band is wider and the midrange has woken up considerably.
I was concerned that the low end launch would suffer but nope not at all as the car still launches extremely hard and I can now feel the boost come on.

Good work. Stay with it. You'll have the 56 dialed in soon.
Then you can move onto the next project with a sense of completion on this one.

To summarize (using your own words):
I changed my rear end and now I launch extremely hard and can feel the boost coming on.

It struck me as funny on first read.

I always thought your rear end was too big.;)

Jr., I haven't had many complaints about that rear...LOL!

Anyway back to the topic, well at least related to the topic. The drive to the shop was plagued by a failure of my fan controller within 2 blocks of the shop. Driving home was stressful fearing traffic and overheating. Thankfully with the aid of my girl guiding me to all the quick side routes we made it home with no issues.
I diagnosed the issue to what I assumed was the failure of the FAN-PWB and confirmed it with SPAL. They no longer build or supply Fan controllers but endorsed the Dakota Digital unit which I ordered.

Well in addition I have been chasing the well known SBC oil leaks which are compounded by AFR 220 heads. I had been running the FelPro Permadry Plus 1628 gaskets and they leaked like crazy. I called AFR and they told me what was also posted on their site use Fel Pro 1604 or they will leak!
I changed to those and still leaks. I tightened the valve covers and still leaks. Paul and I took stabs at several areas and still leaks while under boost.
Finally I poured in some dye and after careful inspection, well and some luck I noticed oil under the outer edge of the rear part of the billet wire looms on each side. How the heck did oil get there when the inside edge was not covered in oil. A little frustrated I lowered the lift and for spit and giggles I shined the light on the top of the engine and to my surprise a tiny trail of oil on the top of the loom and little droplets on the top of the valve covers just outside of the breathers.
Apparently since the covers are polished the oil didn't stick to the covers making it difficult to trace as they were always dry. The seals in the breathers had failed and under pressure the oil would spray out, flow down the polished valve cover onto the polished billet looms and run down the side of the rear of the block. This is why no oil leak trails under the front side of the valve cover gaskets because this time the valve cover gaskets were not leaking.
Well I disassembled the breathers sealed them up with RTV gasket sealer and reinstalled the seals and base plates and let them set over night.
The next day I started up the car and went for a drive around the block then out onto the main drag and punched it. Boost came on then the engine died! I rolled to the side of the road and began to run a diagnoses. Looking under the hood I had fuel pressure but it would not start. AAA flatbed home 3 blocks and into my garage. Tonight I went through a full diagnoses and confirmed my findings with Summit Racing Tech support. My MSD 6AL (6425) digital has died. I ordered a new one and a new 8252 coil just in case. FYI the LED does not light at all. All connections have been checked and there is power all the way up to the box. In addition the unit failed all the check procedures confirming correct 6AL function.
So looks like this week I am not only installing a complete new Fan controller (some wiring changes required) but also plugging in a new MSD 6AL box.

How many years old was the Spal Fan controller?

How many years old was the MSD box?

FAN-PWM was just introduced when I bought it almost 19 years ago. SPAL is out of the controller business and recommended the Dakota Digital unit which arrived last night. Looks like some fairly easy rewiring and relocating the box into the interior (Dakota requires this).

I went through the diagnostic procedure from MSD and the system failed all area. I then went to the instructions and based on no LED light under any condition I surmised it was the 6AL Digital that had failed. I then called Summit Racing Tech support (MSD was closed) and together we went step by step and the tech came to the same conclusion as I did. I ordered a new unit along with a new coil just to be safe. Today I spoke with MSD Tech support and they too confirmed it is likely a failure of the 4+ year old 6AL. They also said to send it in for $88 and they will repair it. I figure this way I will have a spare for very little dollars.

Well I changed the 6AL and still no difference. Well as I am adjusting the Dakota Digital fan controller with the ignition on (required) all the time my fuel pump is working. I turn over the engine and hear a pop. Strange, we have ignition of some sorts here but it will not start. Hmmm! So I go to remove the distributor cap and a screw falls out. Apparently the shop that installed the rotor forgot to loctite the rotor retaining screw (boost style) and that is what the real problem was. I replaced the screw and we are back in business!

Hyper: I always carried a spare MSD rotor, cap and 6AL box in the Gob. I wired each box with a plug to allow an easy swap out. Unplug, unbolt and reverse...done..too many times I had to help friends who were dead on the side of the road because one of the 3 was not operating. Happened to me once. Caps (particularly the center button) seemed to fail way too regularly. Consequently they were regularly checked. I also drilled each cap to avoid the corrosion from ionization.

Hey Paul,
Good to see you back man! Great idea but we don't have the humidity problems we have at home. Heck here if the humidity gets to 75% everyone goes nuts. I explain that back in Maryland/Virginia/DC we call that Spring (when it gets dry and isn't hovering in the 85-90% humidity range).
Well all good now except the overheating issue causing the heads to warp. I dropped the heads to be resurfaced today and have a >30 RA surface on them. I should be reassembling this coming weekend.

I'm back with a '69 Z28 which my daughter bought at a Mecum auction in Vegas. Spectacular rust free sheet metal and Hugger Orange paint and a simulated body-off restoration....

My job is to take the steps to make it a safe, dependable occasional driver and AACA-worthy restoration...the PO went so far as to paint the fuel and brake lines - not replace, paint. It's a correct DZ engine, just wrong date; Muncie is off by 3 years; and there are too many minor details which just aren't right that I'll be chasing them for the next couple of months....

My NCRS experiences with the '61, '62 and '67 Vettes help convince me to avoid the Camaro-only judging and stick with AACA which judges on appearance and condition, not dates...while still making the car enjoyable. Those 30-30 cammed 302's are fun to drive once you get off the line.

Take care. Hope the market remains strong for you.

Hey Paul,
Needless to say I am very envious about that '69 Z28 as it is one of my favorite cars. Keep at it and you will get it right.
My blower motor is giving me fits right now and I am having to practice patience.

The market here is rather strange to most California Sellers and Agents as the majority have never seen or experienced a "Normal" market. They are only used to the Fast double digit annual appreciation growth and double digit valleys. They are used to a short DOM and begin to panic when a property does not have either multiple or at least an offer in under 30 days. Since the market began the turn around we only had one real true double digit year which was 2013-2014. The rest has been a slow, steady and healthy high single digit climb. Since the mortgage rates hit the high 4's-5% the average DOM across the board has slowed way down and in some price ranges are approaching the 45-60 mark and the higher priced are even longer. I think we are in for a reality check of 60-90 DOM with a low single appreciation rate. We just put two in escrow, one lower $600's and one of our $Million listings. The rest are sitting including a low end condo. It all just takes patience. As my grandfather who was one of the very first track home builders used to say, "Homes are just like chairs there is a fanny for every seat". Take care and remember to smile and have fun.
Bob
