The advantage to this is your average poor shmo could lift a 440 out of a New Yorker, throw in a cam and external bolt-ons, and have a genuine high perf setup. Chevy had crap heads on their mundane engines as did Ford, and as for cranks and rods, well, NOBODY built regular old engines as stoutly as did Chrysler. Today this means no hunting around for special (expensive) "double hump" or "angle plug" Chevy heads, just slap on any old 1968-1973 head and you're pretty much there with a Mopar big block.
Right on! MOPAR or no car! I've recently bought a '72 Chrysler Town & Country (pea green & woodgrain) that is going to get the sleeper/"Q-ship" treatment ("who, me? No way officer, it must have been that Camero over there that was doing burnouts, this is my grandma's car....."). It already has the 440 & "tow package" but an aftermarket aluminum dual plane intake, headers & misc speed parts are going to be in the works. I'll admit that a C body wagon isn't what most normal people would consider a hot car but at least I'm not the only one, check out http://www.wagonsofsteel.com/
