Re: More NHRA horsepower factors
I know someone with a 78 Firebird that was building a 350 Chevy motor based on the 269 rating!

Re: More NHRA horsepower factors
1978 & 1978 Malibu Wagon with 350 got Hp. 2 times, once with Camaro & Corvette & the second time with the Camaro & the Corvette did not get Hp. I look up 350 Malibu Wagon in Nitro`s stats, in the last 10 years, The fast run I could find was 6 tens under the old index.

Re: More NHRA horsepower factors
I think they need to hit the 1969 iron head 396-375 Chevy engine again. Its only @ 412 and everybody knows it was originally rated @ 425 in 1965.

Re: More NHRA horsepower factors
What makes the least sense about that 1978 firebird 350 combo is that it has the same specs as a 1977 camaro 350 that's only rated at 269 but the firebird is 283 and was originally moved to 269 but now back to 283. Anyone have an explanation for that? I thought all vehicles of the same platform with the same engines were rated the same. All other camaro/firebird combos are factored the same whether in a camaro or firebird throughout the entire guide. Uncle Jeff what's the scoop? I know you know...lol
