Making power out of the 318

carmart1975 said

the 318 i have is in very good condition just needs a good clean up like a hone, the rods are good and the crack has a Little surface rust i already have new rings and bearings for it i would just get the cam bearings done and i would need to by a oil pan and a front timing cover and the heads would need a full redo because they have like dried up sluge or carbon from the 360 they came off of and i would half to get new pistons because the owner before me droped one and cracked a peace off

Other than displacement with the 5.9l which would help with lack of gear. It's mainly the heads cause there capable to reach 400 hp. Nothing stopping you using the 318 bottom end (but I would run less cam so less power but up to you) and could grab a set from a scrap yard and hope there just need a quick go over or buy a set of remanufacture ones or there's other head options. Which brings me back to the 1st step of your 318 build, Heads 2nd step figure out cam 3rd figure out cr for that cam etc..

If go 5.9l magnum then 1 and 3 are somewhat baked in.
