460 vs. 454
Does anyone have a source for a year by year torque and horsepower comparo between this offbrand bigblock and a 460? ..I'm not thinking about buying anything... just need it for "debate" purposes! Thanks.

460 vs. 454
FWIW, the Doug Thorley web site has some HP and torque curves for the mid-90s Chevy 454 and Ford 460, comparing stock engines to ones using their headers.
There's the Ford 460 graph:

And the Chevy 454 graph:

I've hotrodded both engines and just by the seat of my pants, I'd have to say my present 460 (472) beats the 454. My 57 Chebby Tudor had a built-to-the-gills L-88 that I built with a 5:13 rear and Muncie close ratio -- used to have fun making it jump over coke bottles when dropping the hammer, so it had a "little" bit of o-o-o-m-p-h to it.
I'll have to say the 460 screams like a bat out of U-no-where.... and just about scares me!!....

460 vs. 454
Here is the lowdown on the 77 model year.
454 245hp/365torque 8.25:1 compression
460 237hp/365torque 8.0:1 compression
440 195hp/320torque 8.20:1 compression
The 460 gets worse in 79
460 214hp/362torque still 8.0:1 compression
The moral of the story is; the 454 has 8 more hp but the torque is equal. The 440 Nopar isn't even close.
