1988 460 stock power?
 

Yeah probably a newbie question but I searched and couldn't find the answer... What are the output figures of a stock '88 EFI 460? Also, what are the limitations of the stock EFI system? This motor is going in a truck that will be used for a lot of grunt work and some mild mud bogging/racing. I would like around 400hp, and 500ft lbs...

I have already posted on this, but I'll do it again

185 Hp and 270 lb/ft of torque at the rear wheels, (remember this is going through a C6, NP205 and 9")

which equates in a round about way to about 255 hp and 365 lb/ft of torque

I'm also running with the air silencers cut off of my intake, and dual 2 1/4" exhaust (a little restrictive)

The factory specs for the '88 EFI 460 are 280hp and 410lb-ft of torque at the flywheel.

ok, so obviously I've got alot more parasitic loss that I know of.... lol
