The 445 ci 390 is a stour motor, and likevyou said, a lot cheaper. But, I'm one of those Cobra idiots that have to use what they origional cars had, which of course was the 427 & 428.
Same goes for the 514ci. 8k with 625 HP, but not a FE. Know what I mean Vern.
(I'd have to change out or trade a lot of parts, as I'm set up for a FE. Plus, I don't know if it would fit under my hood, fit in the trans tunnel etc.) ?
550 (+) HP/TQ is a must.
But,.......the 390 is worth thinking about.
Brent, apx.......what you have in a 390 and how much ?
