1987 Dodge D150 pickup 5.2l 318 cid
I have an 87 Ramcharger with a 318. It is a factory roller cam engine with the 302 head castings. I rebuilt it stock except for having a good valve job, factory cast iron 4bbl intake, MSD ignition and dual exhaust. Truck runs like a champ. I would do it again, except for a Performer intake just for the ease of carb swaps without using an adapter plate.
Going from a worn out 2bbl, 318 to a fresh 4bbl 318 was night/day difference in power and driveability. Almost like a 360 was put in its place.
