George's car was bought by a guy who lives in Moline,Illinois. It was running really good, and he blew the motor a few years ago and hasn't been back out since.I understand that he is planning to be back this year, as it is quite a long process to build an engine from scratch.
I met George at the Winternationals about 10 years ago.Great guy with a long history of fast Oldsmobiles.I remember asking him about his car and whose pistons he was running.He said Arias.After he told me that,I didn't ask anymore questions.The small valve and low compression combo is probably a much better combo for Olds 455 racers.

Quite interesting what you posted, but you really should start another thread as I don't see that it has anything to do with LS1 factors.
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.

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

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?

Platform/wheelbase consideration like Ford & Mopar received years ago??

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.
