Your input on 360 stroked to a 426

You dont really think a 9 second car is a stock body and motor.... right? :D
In any event, I wouldnt do it either. You dont need the R3, but it's a wise choice with spray. The pistons on the Hughes deal are VERY short. No life expectancy, and I would think ring seal would suck in pretty short order. I like that Racejunk top end on either 360 cid with big spray, or a 4" setup with less hit.
