big block vs. smal block

If you are starting from scratch a big block would be better although you could run 12's with either a big or small block fairly easily. The BB advantage comes later down the road with increased power potential later.

It will cost nearly the same to stroke a big block with alumunim heads as it would a small block with aluminum heads but with the potential for an easy 100 to 120 cubes in the big block it becomes obvious which one will make more power. BTW an aluminum headed low deck stroker would weigh in the same range as an iron headed small block so the weight issue becomes less of a factor.
