Forged bottom end?

if you want to do it on the cheap, you can do:

03/04 used cobra crank $250
03/04 used cobra rods $300
CP pistons $700

thats good to about 900HP or so. add a set of Billet I beam rods, and your capable of 1300HP.

but then you also have rings, headstuds, mainstuds, gaskets, machine work.

power wise, or $$ wise? i sure hope its not $$ wise, because your not rebuilding your motor for that, its going to cost you more than that in machine work.

if you want to support 650-685HP then the cheapest, and one of the best ways to do it would be, 03/04 cobra crank, 03/04 rods, and manley pistons. your right under $1K, then you need rings, headstuds and main studs. and machine work of course.
