I'm planning on carbing my stock 350 (after some work), but I have a question before I do it. My '89 Iroc currently has a hood from a V6 3rd gen (due to a front end collision) and I'd like to put a stock Iroc hood back on it. However, I'm not sure if a carb will fit under the hood. Does anyone have any idea if I'll be able to fit a carb'd 350 under an Iroc hood? Thanks

 

youll need a drop base for the air cleaner,but it will clear.

ive done the swap,and im still running a tiny gay lookin air cleaner b/c im to poor and lazy to find a 3 or 4 inch drop base for it.

 

It'll work just fine with an IROC Hood. I did a carb on top of a High Rise Dual plane intake(RPM Air Gap), and with a 2 or 2.5" Drop air filter base it still has 1" of clearance. A normal 3X14" K&N Filter is fine. Adding a 1" thick "carb spacer" even works but it took some muscle to close the hood Doing a shorter intake like a Vic Jr. will give you another added inch of clearance.

Doing a breathable filter lid probably helps a lot also with the drop base. If I knew who made the base I have I'd tell everyone about it but it never had a name or anything on it. It's probably Moroso but it has no angles, just a very large radius to lower itself and it fits around all of the linkage and fuel stuff/fuel bowls perfectly.

 

my experience is that vic jr. with d.p. holley will clear; add a spacer or get the tall vic or other high single plane manifold and the hood will clear but itll choke your airflow[and hp] way down[we cut away some of the underhood metal just to close the hood]
drop base wont make a difference if theres only 11/2 in of clearance from the top of the carb[we had a milled choke] to the hood.Im sure itll work fine on dual plane designs and shorter single planes though.

Mine clears just fine with a Performer RPM intake and a 1.5" drop base for the aircleaner, with a 14x3" filter. If you use a shorter intake you can probably get by without using a drop base.
