So in my avatar 31 chevy coupe is a well built blown 355 that rocks. It is 9.5/1 comp. for the 8.71 blower and for those who say the blower is to big for that engine it is underdriven and works very well. My delema is the starter a powermaster mini. Last summer it started skipping on the flex plate making an ungodly noise,took it off an found a bent bolt. But they where tight.Proper bolt with shoulder. Replaced them with new oem. Fast forward a year or so and its making the noise again. the mini is there to clear the headers. I haven't removed the starter yet to check. Any thoughts would be appreciated....Thanks Jim.
