Mill decisions

More power to ya brother! 700 on a stock block seems high to me but I dont know what knid of numbers can be made.

BTW, how fast do you wanna go?

Why not go big block? You are talking a whole lot of $20's to do a 700 HP S/B. Maybe you and I have a differant idea of how much it will take to do.
Don't know, love to see it. Good luck either way.
