Thanks for everyone's feedback so with that in mind this is what I'm hoping for depending how things come out at the machine shop - 383 forged crank -KB240 pistons with eagle rods - ditch the heads I have and use the 440 Source Stealth heads - deck the block as needed for proper quench ( I figure using blue print specs the pistons will be down in the hole .027) balance the rotating assemble figure rest from there
