I got a CVR Protorque No. 5049m from George Anderson at Guessford Machine.

I had an incorrect starter for 5 years and kept replacing pinion gears. After speaking with George for 10 minutes, he fixed me up with just what I needed and overnighted it to me. He was professional, personable, and terrific to work with! I had previously called every local & national speed shop for an FE mini-starter, but no one had one in stock or could get it in less than 2 weeks. The starter nose plate required no modifications, fits the alum. block with the raised block & drain plug bosses, aviad
oil pan and headers.
This starter is available in two versions, the 5049M is rated at 3 hp, the 5049 at 1.9 hp. About $50 difference in price. Someone said Jegs carries the 5049.
