The night before you started this thread I was looking at 318 stroker kits. I thought it was funny you started this thread and the timing. A member just posted the other day about a 340 for sale that was rebuilt for $3900 that dynoed at 270 hp. For 3900 bucks or less probably way less I could buy a stroker kit a set of speedmaster or edlebrock heads port them, use my 318 block and use extra parts I have laying around and make 400-450 maybe more?
