I want to get rid of my flat top pistons in my 86 5.0 so I can install a bigger cam and better breathing heads on my 302. so I had this idea maybe I could go to the local wrecking yard and yank some rods and pistons out of a newer 302. Then I would put them in my motor in my car and toss my old rods and flat top pistons. I would diffenitly buy new rod bearings new rod bolts and piston rings. Would this work?
