Pontiac 455 hp reduction

[Glenn Briglio]

Could someone explain the hp reduction listed yesterday on the two pontiac 455 combo's.

The reduction that got my interest correct me if am misunderstanding the 1989 TPI 350 with the 128 head in a Camaro gets a 4 HP gift (270 for years now 266) but will be removed from the guide 1/1/2023. Someone must be running it but not for log.

That someone is me. I got hp removed and Nhra looked into the aluminum head in a Camaro. There was never this combo. It was an error by Nhra when put in in 1989. But still get to run it for this year.

I guess Glenn doesn't have to worry too much about hurting his combo this year - zoommmm!

So what was the end result of the lawsuit?

I always heard rumors of that lawsuit. I always thought it was a urban legend. Apparently it wasn't. I started going to 30 in 74. Story I remember was Pontiac won, but I heard all different amounts from $10K to $100K.

Did this combo run at the Gainesville LODRS in March 2021? Or is that a misprint?

Wow.
Combo doesn’t exist.. And it’s under factored
..but it’s ok your the only one with combo ...this is fair ?
But it’s only for 1 year. WTF ?
So you can go to a class race and win and that’s ok?
Glad I don’t run his class

Not sure it's all that much of an advantage over what everyone running the TPI 350 in Camaros are doing.
The flat top iron head 1990 is now at 281 most everyone just changed year to 1989 installed dish pistons at 270.

Glenn decided to work with the aluminum head which was 270 now 266 so 4 hp gift but looks like it runs the same class as the iron 89.

Looked hard at this head 10 years ago compared to the iron head: It's a copy with smaller chamber plus point of compression but no port improvement. We thought at the time apples to apples (not considering it's much higher rating 10 years ago) not better than the iron head even with smaller chamber and point of compression without port improvement and thermal characteristics of aluminum the iron head would be better. That was the opinion at the time plus adding higher hp rating at that time: Now a 4hp advantage if it really matters.

Glenn is a smart guy has found something has done the work and gets to have fun for one season with it. Wish him luck.

Being fast showing it off is fun, if your goal is to win you need a second under car where ever you race to be a threat in heads ups, set up to be able to qualify where you want on the ladder then you got yourself a weapon.

Interesting. Was going to ask how a car gets deleted.
