Along with all the AMC race cars we got to play with, my younger brother and I used to race each other all day long at the strip using our two AMX cars. Two different approaches used there, his was a 401 with mild cam, headwork, intake, 2.02/1.68 valves, headers and 4.44 gear. Mine was a 304 with much bigger cam and much more headwork on 1.78/1.40 valves and intake modded too, headers, 5.00 gear. My car weighed 100 lbs. less than his. Both cars 4 speed (his 2.23 low, mine 2.64) and big Holley carbs. Lower rpm all torque motor vs. high rpm small inch screamer, he shifted at 6000, me at 7500. Both cars would run around 12 flat, he was usually slightly over it and I could dip into high elevens on the right days weather wise. We would line up at the strip and usually on street tires and whoever got off the line the cleanest would barely win the race. It would go one way or the other but mine was harder because of heavier flywheel and more gear. He was also better at leaving on street tires as he did it much more than I being the drag racer of the family. I could outpull him slightly if we were dead even going into high gear, but most times he was ever so slightly ahead of me by half a car. I used to laugh at him grinning at me, we would be looking at each other at well over 100 mph.
Loads of fun, I could do that all day long.
Fix the driver first, then fixing the car becomes so much easier..........
