Nearly 600 RWHP LS7 N/A
We just finished an LS7 headed 440 CID motor. We just did a little hand blending, otherwise the heads are stock. It made 593 RWHP and 556 RWT with a fairly tame cam in the high 230s.
This same exact engine made 545 RWHP with AFR 225 heads.
The only other change was from Stainless works headers to American Racing headers.
The car is quite tame as far as idle, surging etc. It just has a "medium" lope at idle.
Quite a difference with just a head and header change.

Thats a VERY small cam for a 440ci monster, hell even I with only a 408ci am packing a bigger cam 244-248. That motor will get past 600rwhp like something fierce if a cam in the high 240's is installed. Now I'm thinking what a little more compression and a mid 250's cam can do!
