I have a running 91 318 you can have free minus the whiplash roller cam in it. it goes in my other 318 next.
need headers?
got all the hydro clutch stuff with a 4 speed or a nv4500 5 speed for it.
nice 8 3/4 that bolts in as well.
even have a set of wheel tubs if he wants to shackle flip & tub it for some fattys.
I agree with your son.. not many running around here in my part of FL.
I am looking to make a 2x gasser out of a 4x4 RC (or W150) so it has a tube axle and leafs up front.
I say go for it! at his age and having something that old is a good start to having a hot rod in his mid life.
