Well, I figured I'd post up an update. The car runs crazy smooth. The boost comes on exactly as planned, and then the fuel pressure plummets and I have to get off it. Ugh! I've tried a few things and found a nasty burr on the inside of the regulator that gouged the aluminum so it doesn't hold enough pressure. I ordered a better regulator from Aeromotive and should have it in tomorrow. The a/f ratio is way too rich and hits 9 right before going dead lean. Hopefully the fuel pressure settles down and I can actually get some damn tuning started! I set up the distributor for 15 degrees initial, 30 total, all in around 2500. The thing idles at 16-17 afr somehow so I should be able to run the cruise circuits really lean and have decent mileage. Once the center carb is tuned I hook the outer carbs back up and jet them accordingly.

You're right on all counts. The bronze was recommended by the cam grinder, but he did say folks get away with the hard steel, just not what he suggests. The gear that died was both cast, and installed out of spec. It was almost .100" too far down! Talk about binding.  The dizzy also has too much up and down slop. I'll re pin the bushing, and new gear in spec. I have those pages that calls out the dimensions. After it has some run time, I'll check on the new gear and see how it wears. If everything goes well, I might swap to the steel when the 1st bronze one gets shoddy. Probably mid next week before I'll be able to do much on it.

Well I got it fired up! It lasted about 5 minutes.  :-[ The idiots that sold me the cam said it didn't require a bronze gear because it's a retrofit roller cam. I called the manufacturer directly and he said it does, for SURE. The distributor gear was hamburger, but by luck alone, the cam gear still looks new. I should have the bronze gear today. I flushed everything out and will change the oil and resume the initial baseline tinkering.

Wow, my old setup is running 20psi with no coupler issues. Maybe crazy tight clamps? I don't know as I sold the car and never ran that much boost when i had it. I think he upgraded the clamps though. I do have 2 different solutions in mind if it leaks boost. Should have the motor back from the shop this week!

Proof load on a single 1/4-20 grade 2 all thread is 1750#, and there's 2 of them. If anything, I could see the bottom lid flexing near the ends and leaking boost. As Drew said, if it leaks, I'll change it.

Well, finally got the parts for the engine. The guides are being machined for positive seals, and the dual springs, as well as surfaced for cometic gaskets. Once the longblock is back together I'll check the pushrod length, and order those. In the meantime I've cleaned up the engine bay a ton. I'll try to post a pic soon.

Thanks again! The rocker conversion is in development. No part of it comes from an existing design. I laid it out in CAD and made the prototype. It worked great all last season before the turbos. Now it will be all roller! I did the same rocker kit for Buicks years ago, and they have worked out very well. One engine using it has seen 23psi and 8000rpm repeatedly. The FE setup is even stouter. I guess in short, it's not top secret, but not quite market ready/ available.

Howdy guys! I'm the guy doing the turbo setup. I ended up going through the motor as I had to pull it to do the oil drains in the pan. I figured I'd freshen it up. It had a slapping piston anyway which I was going to gamble on boost. lol. Now it's getting forged pistons, and a custom roller cam. The blowthrough bonnet is only held together by the 2 carb studs, but I'm certain it will have no problem holding 8psi. If not, I have an idea to add some clamping without any visible changes. Probably still a month out, but rest assured, I'll be posting about it then! I have more info about the build coming on my website too...
