Which engine?

318 will make more power than a 273, all else being equal. 45 cubes in bore is huge, and that's the only difference. Besides, much easier/cheaper to find a good 318. But while your searching, I'd include a 360 into the search. Why not? they hold a 42 cube advantage on the 318, and 87 cube advantage over a 273

My thoughts exactly, but since I live in the north woods, my options are limited - drove 2000 miles to pick up my 'new' 65Cuda... - so finding a 360 might be an issue. The Mob here :mob: seems to think I should use my existing 273, beefed up, and I can figure out something for the old Cuda once I'm done. I could 'part it out' or I can get it running as well, I do have two boys - Don't seem right to have two boys and only one Cuda... But that is a question for another day...

Problem is that if I use the 273 and then find a 318 or 360, I'll probably want to put the bigger engine in the Commando and put the 273 BACK into the original. Guess I'm not sure if that it is a 'problem', maybe that's just the way it is with MOPARs... (:lol:).
