Don't forget besides the dogleg heads, the higher compression. 70 was the only year with both, on all the V8's. And the deck height change in 71 made interchangeability … difficult. My 68 was rough, 60 over, lots of miles, 343 auto, hit in the rear and fixed in someones back yard. But I loved that car. To understand the AMX you must take a drive in one. Mine lost it's life to a 15 yr old girl with a learners permit … in Phoenix Arizona. I still miss it.
