Looking for a 6.4 Hemi

Wow Tincup, that is SWEET!! I had a 67 100 longbed 383 truck that I replaced with a 440. One of my best trucks with sweet memories. Always wanted it to be a short bed but could never find the right components. Finally sold it when a genuine Lil Red Express came along. The 67 had way more character!

This was all just before the new Gen. Hemis came along. The lessor weight of the Gen3 will be killer compared to the big ol' 440. Personally, I'd suggest a 6.1 in there. That would be way plenty HP and torque for that lil truck. A 392 would be crazy in there. Although, crazy can be a lot of fun!

Seriously though, a 6.1 would be much less of a pain in the butt to get up and running and still be overkill in that truck. You'll enjoy the end result either way. Good luck / have fun...
