Big Block pulleys???

[kcandc]

I am restoring a 1968 Camaro that I bought w/o an engine. It was a big block orig. ,and I want to install a 454 I have. Can you put a short waterpump and corosponding pulleys to make it look orig? or does the 454 dampner prevent that. I have heard the 454 is balanced exterally with the dampner. Thanks, Karl It's a mid 70's truck engine.

The 454 is externally-balanced, but the overall thickness of the damper to the pulley mounting face is the same as that of the 427; the 454 will accept the same accessory drive components as the 427 with no issues.

That's the answer I wanted to hear, Thanks, Karl
