81 w150 4 barrel intake manifold compatibility
#6
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.
