how much horsepower does a 454 big block chevy make stock
you are looking at roughley 450 hp at 5800 rpm and 510 to 515 ft.lb of torque at 3500 rpm . those specs are from the new 454's i have no idea how mutch the older ones are . i would half to say that the old style would be pushing roughley the same numbers
The stock 454 i pulled out of my 74 truck was pushing 360 hp and it was stock everything. It had 150,000 miles though so it was a 390hp motor new im sure.
depends on what year............late sixties 454.....about 400hp stock.......but newer than that like seventies eighties or ninteys prolly about 200 to 250hp
the older 454's could put out roughly 425 hp and 450 ft. pounds of torque
youre right on the money for the ls6. without the insurance crap back then it would of been over 500.
my 85 silverado is pushing 450 hp
