Review on πŸš— GM Proform 141-656 10si Chrome Finish 1-Wire Alternator - 70 Amp, Internal Regulator, Red Bowtie Logo by Maxwell Thomas

Revainrating 4 out of 5

great product for starters and alternators

This alternator was used on a 74 Nova with a 350 SBC and is direct bolt on. At first I thought it wouldn't work, found that some fuses had blown after I reconnected the ground clip to the battery. The only problem I have with the product itself is that it doesn't start charging until the engine hits 3000 rpm, but after that it works fine at any engine speed. He also completed the engine with a look.

Pros
  • Excellent overall performance
Cons
  • Mostly good but...
