What made A bodies non-popular

ok here yall go its on b bodies ( go figure i hunted all over yahoo and google) theryre arguing over A the color, first one gloss black the next ones are flat black. B someone wants like 130k for it? and C they are saying it is either a gen 1 hemi which would be a 392 or a newer hemi aka the 5.7 cause in the first one the plug wires run to the back as if its a small block. and the next movie it showed up in was the 4th one and it has a true hemi with a blower. so theyre ya go a movie car that someone wants 130k for that may or may not have a gen1 hemi and may or may not have a new style small block 5.7 hemi but its a hemi of some kind. oh and the thread just poped up like 2 weeks ago
