Thanks everyone, yes car was originally a 318 powered car. I have all the parts needed for 3 different powerplants; 340 six pack, a very stout 440, and 426 HEMI. My main and really only intention was the HEMI, I ended up with the 440 during the deal of the 426 and the 340 is for a Demon I'm gonna build. My dilemma is old school Hemi or modern 392 or the hellacious new Gen III 426. All I've ever wanted was an old school '70 Hemi Cuda, but I have no experience with driving one to really know what kind of quirks or driveability issues are normal to the dual quad 426. I have been considering a fuel injection setup as I've done some of those before and those come with baggage as well. A modern engine would offer same power, lighter front end, great driveabilty and more trouble free. It wouldn't have the menacing look of the elephant motor under hood.
