Damn...305 superstock engine receives 15 hp.....

[Chevy55]

10/20/2020
As the result of runs under the Automatic Horsepower Factoring System (AHFS) 1.20-second under policy at the NHRA Division 2 event, the following changes have been made.

The horsepower rating for 88-92 GM Camaro/Firebird, entries with the 305 cubic inch engine and a factory rating of 190-210 currently rated at 240, have been increased by fifteen horsepower, to 255 horsepower; for Super Stock Eliminator.
NHRA's 2020 Automatic Horsepower Factoring System outlines that any run of 1.20-seconds or more under the index will receive an immediate index decrease or horsepower increase. These changes are effective Oct. 20, 2020.

Yes the B4C police package was a Z28 without the Z28 emblems, 1992 and up all had 350 power plants, except the 1991s had a 230hp stick LB9. The B4C was never put into the classification guide, my guess would be because they were never offered to the public. If the B4C was in the classification guide I guess you would have to have blue lights on the car lol.

Plus the 1987 305 190/240hp should have received the same HP hit as the 1988-1992. The 1987 Z28 no longer shows it had this engine in the classification guide. The Classification Guide is becoming a joke!

I stand corrected, the 1987 Z28 305 190hp has the same head casting number as the 1988 thru 1992 Z28s, but the 1987 head is 1cc bigger in the combustion chamber than the others per the guide.

I don't like to speak for my brother but he don't do the internet. He received a gift of some horsepower in SS/GT earlier in the year. The offender laughed about it and said he don't run GT and didn't care. My brother spent thousands of dollars and had his Firebird changed from a 92 to a 87 Fromula with circus paint from Steve Mc Creary so he could pay back the favor. The car was entered at Rockingham as an 1987 Firebird Formula. The pass on the car was pretty weak as the 60 foot was a 1.38. David said he cracked the thrtottle and the MPH was maybe 131. Dave ley came by and sealed the engine. I convinced my brother to tear down early and not make a run that could have easily picked up a tenth. Every one picked up a tenth the next morning. I figured he still had a an easy 1.25 under after the horsepepower.The next morning it would have gone in the 9's in ss/la. Why the 1988 to 1992 305got the hit I don't know.

GT motors should get the same extra HP hit everytime a SS engine gets hit... it only makes sense.
They made separate GT HP ratings because of body style advantages in the GT car.
You can't have SS cars with more HP than the GT cars with same engines.
I can't believe this hasn't been corrected for years.

Of course, if that was changed, then the SS cars would also get hit when GT is hit if the rule was universally applied. I don’t see that changing

Not true James... this only goes one way. (SS car goes fast- hit GT hp too)

3800 lb big air grabbing chevelle (or worse- some big wagon) running SS. Racer takes that motor combo and puts in GT car (cavalier?). Definite advantage for the more aerodynamic cavalier.
Thus, GT cars were given a separate HP from SS cars. If a GT car goes fast, it should not effect the SS cars (only SS cars going fast should hit both HP'er)

GT HP should NEVER have hp lower than the SS same combo.

But you are right about one thing.. NHRA probably won't change it... BUT they should.

Tom, what about a car that can claim SS and GT with the same engine, same body. The LT1 is 295 in GT and 279 in SS same body same engine? L98 Camaro's do the same thing, can run both classes with same car and engine. Either they both get hit or they stay separate. The problem is a car that has the correct engine in it should have not been allowed to run GT, but that bridge has been burnt down long ago.
