904: should I switch to 727?
I am a 727 man. I'd destroy 904's with Horse power. Just think how long a 904 would last behind a 440 or a Hemi. Probably why they never offered any Big block 904's. If your lacking that much power to turn a 727 keep the 904 and rebuild it more often. Put a 7 1/4 in much lighter also.
