Guys really am stuck here on where to take my car next I will give you a quick rundown. I am finally after 2 years getting my 71 nova shipped across the us to me it's 250 is pretty beat up at this point and I am definitely going to tear down the car and rebuild it and just can't decide to keep the 250 or put in a 4200. I know somewhat the pros of the 4200 but the fact I already have a full 3" exhaust, headers, Clifford intake and Holley 390 4 barrel on the 250 is making me think for me sticking with the 250 and rebuilding the engine and getting head work done would maybe be more worth it then actually doing the 4200 swap? What are the thoughts I am looking for just a weekend warrior car here for fun running a turbo and putting out good hp.
I have no problem doing fab work and can weld pretty well so all modifications for the swap and adding the turbo won't be a problem
