SBE 318 basic rebuild +CAM , INTAKE, HEADS, expectations?
can't suggest a cam without knowing all the other information. otherwise it's shots in the dark.
but you want my wild *** guess? 450 or lower lift and 260 or under duration on a 112 or narrower LSA, split pattern over a single pattern. based on what you've got there.
i'm not trying to be a **** head, i don't know what your skill set is or how many motors you've built or whatever, but it's pretty well established that .500 lift cams with nearly 280 duration don't do well with small stuff. small cubes, small compression, small gears, small stall.
now take out the trash and finish up the dishes before you go play mopars some more!
