I recently bought a copy of Nitro Joe's Stats on Ebay.(Nice job by the way).
I really wasn't aware of some of the horsepower factors in some of the classes I don't compete in.
It appears that there is an LS1 in some bodies that is at 381.
Then there is a manual transmission combo that is something like 40 horsepower less than the 381 of the same body.
Then,if it is in a Corvette,you see 350.But in a Firebird, it's 381
Are these engines all the same or are there differences?
