Although it does look like they are consolidating factors and giving the engines the lower ones. So the LS1 Firebirds that are at 381,should go back to 340 along with the Corvettes using the same logic. |

Re: LS1 Horsepower Factors
George Thomson passed away of Covid in Dec. 2020 in Lake
Havasu Arizona. I was best man at his Wedding years ago. He was a close friend and a lot of the reason my cars run pretty well even today. He also ran a Killer 73 Mustang 351 that was 1 qualifier when he wanted it to be. There is nothing he could not make fly! He called me the day he died and told me he would not make it to the end of the year! I talked to the new owner at St. Louis points race two year ago = Nice Mature Gentleman and it was running fine then! RIP

Re: LS1 Horsepower Factors
Well how the LS1 GTO landed in F/SA @3740 lbs and 40HP less is interesting for sure not as aerodynamic? No Ram Air?
But its not the GTO that's been feeding on their GM cousins Camaro/Firebird, It's the LS1 C5 Vette. Heads-up about 260lbs lighter....who needs ram air? |

Re: LS1 Horsepower Factors
As a person in the process of resurrecting a E/SA Camaro it wouldn't bother me to see a few horsepower added to the GTO's.
