What would be a good aftermarket intake manifold for a stock LO3 on my 90' Formula. Any help would be great. Thanks.

 

Edelbrock Performer TBIworks fine on a stock motor, or slightly modified.I'm using one on my 350 (that replaced my 305).Part#3704,$209 from Summit.It's 1/4" taller than stock, but mine clears the hood with a 14x3" air cleaner.

The edelbrock performer TBI, I have one off my truck!

 

cool. Thanks for the help. What kind of power could i expect to gain from this mod?

 

I noticed torque and pull thru the middle. LO3 heads suck a*s no matter how you slice it though.
