Ihave a 1972 351c with 2bbl heads. canI put a 4bbl intack on it

 

yes, a 4bbl intake made for 2bbl heads (like 99.99% of aftermarket intakes available)

such as edelbrock dual plane performer part #2750* (idle-5500 rpm) or the weiand single plane x-celerator #7516 (1500-7000 rpms)

 

uhhhh, idk, i didnt think you could, y else would they make seperate intakes for 2v and 4v heads?

 

yep just buy the right intake for the heads that you have!

 

Of course you can. Here is some educational reading.

yes you can, the stocker will have a big port mismatch but will work, buy an aftermarket 4bbl intake made for 2v heads

 

i thought that the bolt patterns were th same

 

Even if they were, ports need to match...

 

years ago when there werent aftermarket mani's for 2bbl heads thats what was done, even with the port mismatch it was worth like 15hp
