Aluminum head engine, non. Your looking at expensive stuff. On Iron head engine, just look for a carb intake from a old 80s 2.8l s10. More expensive is the Eldelbrock (spelling) 2.8l carb intake for iron heads that has changable tops to put a larger carburator. If your refering to TBI to carb, then theres a adapter plate http://compare.ebay.com/like/2610050...Types&var=sbar . Don't know if it will fit clear the valve covers.Last edited by TurboGTU; 08-25-2012, 11:29 AM.88 Beretta GTU turbo . 90 Black ASC/McLaren TGP, awaiting 4t80. 2003 Grand AM se 3400/4t45 daily grind.

When you say efi, do you mean MPFI? I guess you could. If I remember correctly that intake is two pieces so maybe you can remove the top half, and make a template of the bottom's mounting base. Then locate where you want your carb and mock up the mounts for that. Then maybe get it welded up in aluminum. All in all it would be time intensive if done right, but hey if you want to spend your time constructively there you go. Not to mention going from those long runners to a carb setup would probably really hurt the idle and low end driveability.

the FI runners aren't really designed for carb use, sure it'll work but a properly designed carb intake will work much better.
