FWIW - I for one would put in what ever you have the means to install. I have a 350 Chebby in mine and would not trade it for another motor. (keep in mind I am a "Ford Guy" by designation). Just because I have a brand preference and subsequently know more about that brand than any other does not mean I stick to it. I actually traded my 66 lowered short box F100 for the Gremmy. The truck was a very nice driver, but I wanted to go fast so I swapped it for the SBC powered Gremmy. I knew both vehicles before they became mine so I know how much was spent on parts etc. the gremmy had about $4500 dumped into the mouse motor alone and is very healthy, can it be done with another brand? Sure, just a preference I suppose I just happen not to care much as long as the end result puts big stupid grins on my face!! I also think a lot depends on your lo-cal and who you know. AMC stuff is somewhat a rarity around here. Chevys , Fords, and Mopars are very prevalent. I can only recall seeing one AMC at the last few local shows and that was a tunnel rammed 401 late '70's or so AMX (or clone or whatever), that includes the St. Ignace, MI car show last summer, I do not recall any AMC's in the show. Next year there will probably be one, but it will be Chebby powered:). I also do not know a single soul who is into AMC's, but for me ignorance is bliss because I have a fairly fast reliable car without the difficulty of finding *stuff* if/when something does break. The only thing "factory" about my motor is the block and main caps anyway. Well, it is as reliable as a solid roller cam motor can be... I broke one rocker arm (Harland Sharp) last summer. Just one guys varied opinion that should have no bearing on what you choose to do with your car. Chris 1973 Gremlin SBC
