I can name several Pontiac engines that were increased by NHRA, then later reduced by NHRA.

So, are you trying to say that once NHRA has increased the hp, they can't later come back & reduce it ?

If a racer causes the hp increase then no it can't be reduced. If Nhra increases hp before it is introduced into their classification guide then yes it can get a reduction. Hope this is correct from what I was told by Nhra.

So if the combo is deleted because GM never made it how is it that the Yenco Nova withe 350 LT 1 IS in the Guide Book

That is the way the rule works now. If a certain combo gets HP then it is never eligible for a reduction. I was told that first hand when I tried to get a reduction on my combo. That Pontiac combo was not eligible by the rule as written.

WOW ! 1st time I ever heard that. So, EXACTLY when did this rule take effect ?

Cause I'm positive that I know of factors that were increased, then reduced a couple of years later, & this was in very recent history.

That's all I'm gonna say about that.

And, who's to say NHRA couldn't just change that new rule ? How many rules have they changed ????????

If I remember correctly it was about 3 years ago the change was made. Lonnie Grim did say they could use discretion on the HP ratings.

My Olds 307 in Cutlass did not get reduction because of being hit. In my wagon I received 3 hp off. G body to B body platforms.

Are you saying that Chevrolet didn't produce a COPO Nova with the LT1 350 in 1970? I'm pretty sure that one is well documented.

NHRA used to provide the run data base with averages for each combo. It made it easy to understand their decisions. I wish they would post the date base and averages again.

Back in the early 80's we ran a 73 GTO in Stock with an NHRA factored Hp at 350 non ram air and 355 with ram air . There was some confusion on the factory HP rating which originally came out at 310 , but was later reduced to 290 . Pretty hard combo to run because the parts are so rare .
