Hello all,

I am building a 427 small block (351W) and it has a hydraulic roller cam in it. I got the short block from Probe Racing. I am using a MSD 8578 distributor.

I understand I need to change the distributor gear. That part is simple enough, but trying to get the right part number is almost impossible. I understand I can use either steel or bronze, but bronze will wear at a faster rate.

I need a recommendation on whether to use steel or bronze and an MSD part number for the right gear.

Thanks,

Brad
