Your '62 Pontiac 421-405hp combination was listed with and without the lightweight components, which we do not have in the current Class Guide. In 1969, C/S was an 8.50 break; in 1970, C/S was an 8.00 break. The lightweight component car would have made C/S easily @ 8.57 factor.
Odd items:
1) I cannot find a listing for the '68 Dart SS Hemi car.
2) The ZL1 '69 Corvette is in the guide
3) The LS7 '70 Corvette is in the guide

Hi Dwight et al yes I am still working on my old 1960s NHRA compilation.
There is another pair I am having trouble with, maybe you have a way to look up the NHRA weights and (Factored) HP for these cars back circa 1964-65.
Two engines:
* MaxWedge 426/425 - I am assuming this was not factored so stayed at 425 even though it made a bit more than that.
* 427/425 HiRiser - I am using a factored HP of 465 just to make things fit but that is a guess. Today's NHRA factors the HiRiser between 420-460 hp depending on class. Reality was it was over 500 hp even back in 1964-65, so I wondered how NHRA factored it back then.
Car weights:
Mainly looking for what NHRA said back in 1964-65 about the LightWeight Galaxie (LWG). NHRA today has the 1963 LWG at 3320 lb, and the 1964 LWG at 3748 lb. The bodies are near identical, so that's over 400 lb of difference. I know some of the lightweighting parts changed but here is my logic in asking this stuff:
* The meager real 1964-66 data I have on the 64 HiRiser LWG shows speeds of 121 mph for the auto trans (a doggy Lincoln unit) an 123-126mph for the stick car. That's getting up there near Thunderbolt speeds, so I wondered if the car was really as heavy as 3750 or if the old spec was different.
* In Larry Davis' book, I know he is not a Ford buy but he says on pg99: "However, the LWG fell right into the extreme top of AA/S, where they not only were competitive, they dominated".
Well, I get a W/P of 3748/465=8.06, which is a long way from being at the top of the AA=7.00-8.69 class. So either the 64 LWG spec was quite a bit lighter than 3748, or the factored HP was quite a bit more than 465, or the quote is just wrong.
Wondered if the OLD NHRA weights and factored HP could shed any light on this. Thanks for your patience for those who read this far.
