My last race car was a '70 AMX S/ST. It had a 451" mopar engine. Low deck 400, 440 crank and rods. Ran 9.90's@133+, 2850#'s. Great wheelie machine with only 11.5x29.5's and ladder bars. Hooker B body headers and a motor plate were all that were needed for the swap. A Hemi wouldn't be a problem. In fact, somebody built one as a pro-street.

I find this to be an interesting discussion and this situation could at some point have some ramifications.
If you compare the Mopar any hood go’s situation (which I don’t think this is the situation, it’s just the tech guys probably don’t know any different they are not all walking encyclopedias of car facts) to the Pontiac combos I run the true defining difference between a “Firebird” and a “Formula” are the hoods. And at least with my stuff between the Firebird, Formula and Trans Am the same motor has the same rating in each of the vehicles. HOWEVER the shipping weights are not the same. If I want to run K/SA I have to have the flat hood or it’s not a “Firebird” with the Formula hood I can run L-N/SA but not K due to the shipping weight deal.
Going back to the Mopars I took a quick look at the 71 Challenger and the Base model and the R/T have different shipping weights and I think some of the motors were available in both models and like my Pontiac the hood is the main difference in appearance. Looking at how the weight breaks divide out I did not see anything that was real close where the hood would make a difference in the class it could run but that could come some day with horsepower adjustments. So maybe not a performance advantage other than hood weight but the situation could affect what class you can run in.

71 Challenger base model would have been a Slant 6/3 speed car with probably a 7-1/4" rear end. The R/T would have at least a 340/727 and 8-3/4" rear. R/T also got bigger brakes and sway bars. Lots of weight difference there for sure.

Trying to handle that sounds like Wild Willie Borsch and his one-armed approach with the legendary AA/FA roadster years ago. So go for it already!

I know of two that were competitive!! Markusic & Huntsinger from Columbus, Ohio took the hemi out of their 67 Super Stocker and put it in an AMX. Also Ray Snowden of Ashland, Kentucky. Both were in the mid 70's.
