LS1 Horsepower Factors

I can't believe this thread has gone on as long as it has but let me clear (??) things up - and remember this is coming from an LS1 Firebird and '04 GTO guy - first , the engines are the same - period.Second , there are sticks and auto's.Third , the bodies in the Corvettes are the same except for yearly changes and none have 'Ram Air'.Third , and lastly the Firebirds are the same with minor body changes and some have 'Ram Air' . The '04 GTO didn't have 'Ram Air' .

The biggest thing I see is some have chosen to keep their foot down all 1320 feet when the air was 'super' .And at times ungodly 'super'.Kinda like what happened to the LT1's a few years back .

As for the 455 Olds combinations I have had none but I do know they haven't been a real factor in Stock since the seventies and eighties .How do I know ? One of my best friends and business associates was John Troxell who had much success with them and had factory support .Also he more than likely invented the phrase 'grey area' .
