Yeah I was always sad to see the brands die out, AMC, Oldsmobile, Pontiac, Plymouth etc. too.
I don't take my cars to the track anymore but I am pretty sure this AMX would be in class against my old GS (high 14's in the quarter), Judge (13s) and LS6 (13s)... probably low 14s / high 13s (at sea level) as is? Braking and handling it might be the best, not 100% sure - no real data, but it feels good in that area (lighter car). I don't "hotrod" anymore, the hobby has really been impacted for that as the collectors took over so, sadly, I likely won't be experimenting with cams etc. in my AMX. All my other cars I experimented like crazy and tried different combinations etc. AMC had a Group 19 program with their hot parts, like the Buick Stage 1 and 2 program or the Mopar "Direct Connection" program. If I ever come across NOS Group 19 parts at swap meets I will grab them for sure and maybe install some of the parts. Honestly though, the car is set up really well from the factory as is, certainly good enough for anything I am doing with it.
