Doug, not sure, but I wonder if since at that time, Pontiac was the "official car of NHRA", if maybe Pontiac offered a higher manufacturer contingency payout ?

Short answer to your question above is yes because it doesn't give that combo any performance advantage over my combo. The weight classification will only affect the natural class and what other two classes they can run. The HP factor stays the same.

My combo was affected by the change, but I am still able to run the same class as before. I just cannot go any higher or quicker classes at this time.

It does give the combo an advantage that it can run in a class that it shouldn't be allowed to run if the shipping weight is not correct. I'm not claiming to be a shipping weight expert.... but it helps the entire LT1 combo avoid heads-up runs and HP adjustments. If it's not an advantage, then why not just go to GT rules?

Please explain the bolded part. How does it help the entire combo avoid heads-up runs and HP adjustments? There are a lot of fast cars in A through E. The 2015 VIN Camaro and LS1 Vettes come to mind plus many others IE Larry's combo. There are a lot of them out there.

It appears to me that this aspect hasn't changed one bit. Another question. Do you think the LT1 automatic combo needs another HP adjustment added to it?

This is a real easy one to explain so I’ll tackle it! Firebird can run SS/HA, Camaro can’t! So when they race each other, let’s say in the final of a national event, or a must win round in a points race, they won’t race heads up! Therefore, neither will have to lean on their combo, which is the same in both cars, to secure that all important round win! So they just race each other in bracket mode and continue on with the same factor. Allen, is that a good explanation???

I see your point, but I was referring to stock and the fact there are a lot of LT1 combos competing in the classes I referenced. It seems to me that leaving some of them whether I agree with the carve out or not actually expands the possibility of HP adjustments which effects the entire combo no matter class chosen.

Bingo.

Edited to add: I'm not asking for changes in HP ratings. I'm working on my stuff like you all told me to do.

Ya know, Yac and I don't have these problems with our odd-ball, POS stuff.
Maybe WE'RE not the crazy ones!

This has been discussed before.
