Well, it looks like my stock starter is finally ready to crap out. I was told at the machine shop that because the block was running 10:0:1 or 11:0:1 ratio it would eat through starters. This is now starter number two and when they worked they sounded like crap. These are some starters that i found on the Summit website. If there is a good one not listed, let me know. The truck is a 78 K10 with the 350/700r4/208 combo, headman headers, and it plays in the mud and water.
