........ if i would've stayed 302, i would have definitely went with a 347 stroker with some kind of boost, you'd be making just as much power as a N/A 460. Even if you went with the 460, you'd have to spend more money to get a nice T-56 and bellhousing adapter with really good internals to hold up, otherwise you'd have to go with a built C4 or C6 like me. And having only 3 gears isn't that fun, if i get on the freeway i am at 4500 rpms constantly at around 70mph also because of my 3.73s. Like i said before, you can go find a 460 block at the junkyard and build it up with exactly what you want. I started out with a 1968 block and heads and made it into a very nice streetable hot rod for around $6000 and it took me 3 months to get it all in the car.
Theres only 2 things i really hate about my big block fox, all the damn tire rubber on my rear quarters

and people always asking me, how the hell did you fit that monster in there.
Good luck whatever you decide. Later.............
