1991 454 Big Block
I have the opportunity to get 454 big block out of a 1987 fuel injected truck. The motor was rebuilt 40,xxx miles ago. I was wondering if this would be a good canidate for use in my '69 that is originally a small block. It would of coarse be converted to carb-but i was wondering with a little head work or even new heads would it produce good power similar to earlier big blocks...or would I be wasting my time.
Thanks,
Andy

Andy i would go for it!! Big Blocks are getting harder to come by at reasonable prices on the running ones!!
No replacement for the displacement of cubic inches!! I love big block cars!!

Turbochargers, Superchargers, and Nitrous are great canidates for the replacement of cubic inches

I'm pretty sure the newer BBC's had the lackluster "peanut port" heads. Thses were the smallest ones and aren't very performance friendly. Try and get a hold of some larger "oval port" heads, or some decent aluminum heads and really shave some weight off!
Some NMCA guys have gone 8's with GMPP aluminum BBC heads and flat tappets BTW.
