You do realize that AMC literally made nothing on their own right? Just about every part on any AMC is from some other manufacturer.

@@captainredneck0683 dude u r beyond clueless. Straight sixes and ALL V8's were AMC period. Yes some parts i.e. Motorcraft carburetors etc...

So I’m very much a ls/lt guy, but the guys are right in the comments. For this build a 401 would have been the way to go. Like they said in the show, guys love these things or hate them. An ls swap just makes the lovers hate one of their own. And where did the 8500 ripums go? For one on a 401 that would have been legendary. If they got that to spin. (They got the cash) and for two on that motor it was only a cam and maybe springs(if they were not already good enough) away from 8500. Love this show, and a good ls. So not hating on it.

I am not 'anti-LS' - but it is sort of like 'everyone' wants to drop a BARRA into something - in the end - the novelty of LS and BARRA into everything sort of wears off (albeit the BARRA not quite as numerous as LS swaps - yet - HA). Would have been a pleasure to watch an AMC being given the 'modern' stuff. Have a nice day all - stay safe. CHEERS from AUSTRALIA.
