Re: Anybody build a 427 with a 454 block & 396 crank?
I built one with 454 block 30 over, closed chamber heads, 10:1 compression, and mild 268 XE Comp Cam. It made 491 Hp and 546 ft/lbs at the crank. It’s going on my ‘67 GMC project. Should be fun on the street!

Re: Anybody build a 427 with a 454 block & 396 crank?
I would go full roller. Simply for the fact that today's common part house available oils do not support flat tappet cams.
This way you can run cheaper oil with high reliability, and after a few years the savings would be eaten up by higher cost oils to make a high performance or higher tappet pressure on the cam lobes last with the needed zinc. I dont know if this is true but supposedly VR1 racing has less zinc now, and diesel oil is almost down to modern oil standards. Which won't support a flat tappet can at the spring pressures nessacary to turn a BBC to 7000rpm. |
