Question WRT crank pulleys....

[Back N Black]

Ok, i have a 67 440 block and the crank pulley is in rough shape, it measures 6.5 in diameter. I have another pulley that is a little bigger it measures 7 1/4 any issues other than slowing down the accessories?

Thanks

You can always pick up one from 440 source

If the pulley is from a later model it might not fit the offset pattern on the crank. They changed patterns in 72.
