454 or 427 for 70 Chevelle?
Hello all, I have a 70 chevelle that I'm restoring. It's a plain jane 307 at car now, but I see a big block in it's future. I was thinking a 454 or even a 496, but a friend of mine insists that a 427 would be best. I've never owned a big block, and the only two that I drove where a worked 396 in a 66 impala with a 4spd (2.20 1st) and 2.73 gears, and a 454 in a 66 impala with a richmond 5spd and 3.31's. The 454 was a stock rebuild (with too many miles on the rebuild) from a 75ish suburban.
The argument was raised that a 454 doesn't rev as fast as a 427 and therefore it'd be slower. I said that's fine in a Nova or a Camaro, but in the Chevelle I'd want more torque.
Also there is the issue of it costing more to build a 427 as cores cost more. The other way is to use a 396/427 crank in the 454, but if I have a complete 454, why buy another crank... Just thought I'd kick the idea around a little...
