Intake Manifold option for l83 Crossfire?

Would anyone know where I can find an aftermarket performance intake manifold for the L83 Crossfire 350 Small Block I have in my 1982 Corvette? I can not find anything that's an off the shelf fit for this engine. IN fact, I can't even find a stock one new or used! This is the next piece of the puzzle once I get my car back from the Kooks Header Company, which is installing a custom exhaust for me now. Coated 1 3/4 exhaust headers running through two high flow cats straight through to the back. No more feeding to one cat and back out to two exhausts! Now it's a true dual exhaust but won't be complete until I can figure out the intake problem I have now.

Worst case, I want to get a used or new manifold and have it bored out to open the runners and free up the air flow a bit. I can't really do much else until I figure out this mess and any help here would be greatly appreciated.



:confused: in Brooklyn...lol.

Thnx for any help you might be able to offer.

find an old Offy cross ram (they still make them) use TBI adapters and you wil have to fab a linkage but that will be way cool....

Thnx guys. That intake was already sold but I'll keep looking on E-Bay. I'll also look into the Offy alternative, which is the first I have heard of this possibility.

Thnx again.

Have you looked into the X-Ram intake. They are available for the L83 and supposedly offer 40% improved air flow.

Here is a site with used parts.

Thnx for the suggestion, which I will keep in mind for future possibilities. I just had the stock intake manifold ported and polished by O-FL MotorSports in Florida, which has opened up the air flow pretty good. I am getting a KOOKS Custom exhaust installed this week, which will make it a true dual exhaust with 1 3/4 inch headers (coated too). I have all the other stuff, like the chip, low temp thermostat, etc; therefore, I may move onto a performance ignition and swap out the cam for a slightly longer duraton version and 5:1 rocker arms and see how that works. Haven't looked into the cams and option yet until I see how the intake and new exhaust work out. I'll keep you guys posted on results by replying to this thead if you are interested.

Thnx again and also thank you for that link for the used parts.
