Default What would a 383 LT4 Put out?

Numbers wise? Friend has one built and he's decided to go in another direction.

It's my understanding that it's pretty much a stock headed engine except with 11:1 compression and a 220/230 112LSA cam. What kind of power would it make? Better question is what kind of torque would it make? 400hp/450lbs of torque?

So are they stock LT4 heads???

I they are, frankly I wouldn't buy an engine from someone who would make such a POOR CHOICE.

dont go by dyno numbers that much for example my LT4 only makes 451 rwhp and 366 rwtq and it went 10.73 the first time out with it(near full weight 3450 lbs)
with some weight reduction and a better 60ft and some more tunning I think it will go 10.30`s


that combo should make close to 400 rwhp

Without knowing the lift on the cam and all other supporting mods I wouldn't venture a guess on hp...FWIW I make a whopping 375 rwhp on a Mustang Dyno...but track numbers are in my sig...

Dyno's on auto/stalled cars can mislead. I made 400 on a Mustang Dyno with slicks. Car now runs a 11.5 (bogging) on motor and a 10.42 on a 100 shot. Combo combo combo!
