I was wondering what other 318 has a 4 barrel intake that would bolt to my 2 barrel intake. This is not a daily driver

 

Not bolt to it but replace my 2 barrel intake

 

Edelbrock makes an intake that will bolt in place. I did the 2 BBL to 4 BBL swap back in 2001 on my old 84 RC with the 318. Not sure of the part number.

 

Ex police car smallblck out of like 83-84-85 Fury had a 4bbl on it.

 

I have an edelbrock performer 4bbl intake that I was going to use on my 318. I'm not going to use it. If you want it send me a message

 

Any 318/340/360 4bbl manifold will bolt up.
318 has smaller ports
340/360 have bigger ports
Mine has a 360 4bbl manifold and it works fine.
Paid $30 for it at a junk yard. Better than 300 but those manifolds do work a lil better due to the way there designed. If you got the cash i'd go aftermarket. If your tight on funds pick up a 360 4bbl manifold. But your limited on the carb too due to the bolt patter.
Mid to late 80's 360 with a quadrajet would be your best bet.
