the one with chev in it is because he didn't know how to work on or make a amc motor run. so that one is crap.
the second video was great, he also made a few un knowing commits
1 the shoulder harness/ seat belt was std. on all AMX's
2 the bigger radiator was std on all AMX's
3 NHRA set the hp on all 390 amc engines at 350 hp not the 315 as factory.
4 a complete restored 69 amx was just sold on Barrett Jackson for $61000.00 and a year ago a 1970 AMX for $75000.00

how do i know amx1397= amx the car,,,1 for the first amx off the production line,,, 397 as the (number) of AMX's that i have owned. jim
