Bill...Again, thanks a lot, great program! Using the '70 AMX @ 3223 shipping weight and the '69 390 cross-ram engine, the program illustrates how not all cars (John Lang also) are not suitable for SS/GT. A SS/B cross-ram legal '69 AMX is 610#'s lighter than the GT/AA equivalent, thus, can never be a player. However, if you drop a '69 AMC 290 into the '70 AMX with an auto transmission for GT/LA, you would have a seriously decent SS/GT car, even against the late-model sheetmetal. At least I think so...and there will always be advantages to using the late-model FWD conversions.
Since I'm a stick-only racer, GT/L is hampered by a .25 harder index over GT/LA.
Guess if I ever want to race with a pair of Holley's on my 390 I have to switch the front-end to a '69 model. Someday.....
Everybody needs to add this program to their favorites, especially NHRA!
