There are 2 454 engines for that year.
One is a HD / Heavy duty engine and Avertised Horsepower was: 240HP @ 3800 RPMS.
The other one is not a HD engine and it had 245 HP @ 3800 That is right out of the book.
I think it is around 160
375
303 HP
170hp
200
how much horse power does a stock 4.8 liter vortex Chevy engine have
Chevy Caprice power rating for that year was 170hp.
You need to be more specific. What model and what engine size.
Need the YEAR and what it is in to answer that question right.
Depends on the engine and what you have done to it, stock is about 230 Hp.
Somewhere around 230hp
I would venture to guess about 230
