Review on Enhanced Performance: Moroso 38770 Harmonic Balancer Bolt for Small Block Chevy by Phil Kowal

Revainrating 5 out of 5

Perfect for my late block 880 350

Perfect for my late GM 350 with Scat 383 stroker crank. A parts brand you can trust and it's good to know the quality of the bolt is top notch and the thread pitch on the Scat crankshaft is non OEM.

Pros
  • Package Weight: 0.2lb
Cons
  • Modern
