Good starter for the money
Style: 18493N
Starter works great. It is fitted to a sbc 383 stroker/700r4. Was easy to install and comes with multiple shims for adjustment.

This starter was sold at a great price. I was kinda Leary on buying it at the price advertised at but went with it. It bolted right up and have had no problems with it.
