Re: LS1 Horsepower Factors
Ever seen the specs on a 455 Olds?

Re: LS1 Horsepower Factors
Your point? If it was such as easy combination to run way under...everybody and their brother would have one. Fact is, there are only a couple in the whole country that are active, myself included.

Re: LS1 Horsepower Factors
Cool yer jets Jim. I've been an Olds guy since high school. My comment was meant in respect to an LS combo. Yeah, a 455 Olds is pretty good when compared to other combos of it's era but it's no LS.

Re: LS1 Horsepower Factors
When was the last time that the 455 got HP?
Has anyone gone a second under in the last ten years with one?

Re: 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' .

Re: LS1 Horsepower Factors
I don’t know what 455 you guys are referring to but a quick look at the guide shows the last time one had an increase or decrease was 2008.
That being said the late George Thompson raced a 1972 Olds 442 in G/SA with a 455 and could easily go a second under if he wanted to. I don’t have the answer but I do know I run the combo that has the greatest chance for success.

Re: LS1 Horsepower Factors
At the PRI show this year I had a conversation with Lonnie about HP. I suggested that those two questions need to be applied to the older combinations.
(It is quite obvious that a lot of combinations got beat up pretty badly a long time ago and need help to be competitive again.)
