I am really just looking for HP-FACTORS, ie engines where NHRA changed the ratings. For example the 428cj was 335hp from Ford.
NHRA factored it to 360hp.
Then I THINK they factored the flat-hood-non-ram-air version to 340hp, I know it was different than the ram-air.


I think stuff like the 302z28, Mopar 340, Ford 427, Chev 396/375 and 427s, Chev 350/255 LM1, maybe the LS6 and 455/w30 also got factored pretty quick.


That's really the info I need, hard to imagine they could change all the shipping weights so I assume the online stuff today is as good as any on those.


Thanks if you can list any of those factors!
