I have 2 318s that both run well 1st is a 1972 in 3/4 ton 4x4 pick up... the second is a 1988 1/2 ton 2wd pickup motor.. is one short block better than the other? is one set of heads better? I Don't know the specifically what cam I will install but it will be a small RV type Think like an Edelbrock performer cam, My understanding is I will need to change the oil pan and pick up to fit in an A body.. Will the pan and pickup off the 360 in the car work and do 318/360s use the same flex plate? Thank you
