Does anyone know what HP rating this engine might have?
IIRC 450hp
The LS6 was rated at 450hp, the LS7 had a big jump in compression and a lot more cam shaft.
I dont know if they ever put a HP rating on the LS7
I stand corrected, I knew one of the LS motors was 450....
quick search finds : http://www.chevelles.com/forums/showthread.php?t=203988
states 454/460hp LS-7. Probably drasticlly underrated
ok fellas, a little LS knowledge here
:edit: these are the Gen3 and Gen4 LS motors. the 70's stuff is a bit um (old) beyond my knowledge :p
child of the 80's, what can i say?
LS1: 5.7L, rated at 300-330 hp
LS2: 6.0L, rated at 400 hp
LS3: 6.2L, rated at 400-435 depending on vehicle
LS4: not yet
LS5: pretty sure it's a fwd version of the ls3, for the monte carlo SS (could be wrong on this one)
LS6: 5.7L, 405 hp, C5 Z06 motor
LS7: 7.0L, 505 hp, C6 Z06 motor
LS8: not yet
LS9: the big billy bad ass, 6.2L (383 cid) supercharged. 620 hp, C6 ZR1 motor.

Seems if i remember,it was an aluminum block?
Is there a difference? car 454 block from a truck 454 block from a marine 454 block?
