I need a SBC intake manifold - Damage/EFI/carb/condition doesn't matter, just needs to have/be:

1) SBC dist hole
2) aluminum
3) cheap

Thanks!

Cowl has a 6" hole directly above the dist. I will fab a sealed cover that will be removable with the windshield in place for servicing wires/cap/rotor without pulling the windshield. The dist MIGHT come out, too, but worst case the Lexan windshield will be removable in about 5min.


I was not nuts about cutting the holes in the cowl, since it is structural, but they just missed the flange to the firewall, and the internal bulkhead, so I'm calling it OK. I considered welding a cylinder in there to connect the top and bottom holes, but with the motor in there it would be a PITA for little effect.

Looking good. I saw the hole in the dash, but wasn't sure how much clearance you would have to the windshield. Heck I forgot all about the cowl/windshield/motor relationship in the earlier posts, until I saw the pics. Then I was like uh oh...."Houston we have a problem".

Could you run on of these? http://www.msdignition.com/Products/Distri...istributor.aspx
Or is there some other concern at play specific to the LT1/Opti?

I was interested in the whole conversion from opti to traditional distributor. My dad has stone stock 93Z28 and I am waiting for that to crap out and tackle that job. I don't think he'd go for this conversion though.

The crab dist may not fully solve the vertical clearance problem, and would certainly create a horizontal clearance issue to to the fuel rails and EGR bosses. Both would be solveable with some fab work, but if it's a street car you have the added fab of a remote mounted EGR valve, if required for local smog. Still, the dist may not come out without a hole at least in the bottom of the cowl, and it would need to be a larger hole, so starts to impact the firewall and internal bulkhead, and possibly center wiper arms. No hole = probably a motor pull to R&R dist or intake.

The 93 is batch fire so you only need one sync signal, electrically it could probably be done with a conventional dist.

This tall dist is a FAST specific with cam and crank position outputs for sequential fire, and the physical size and shape worked ideally for this app: race car with Lexan made the cowl hole a no brainer.
