1964 Chevelle Crate Engine - Ultimate Tanning Machine

The Crate Motor Challenge

By Andrew Schear

Cracking and popping from no mufflers, we ran the motor for the required 30-minute break-in period, keeping a close eye for leaks, oil pressure and loose appendages. As our motor was outfitted with a roller cam, no cam break-in is necessary, however the traditional bearing and ring break-in still applies. We know you're anxious, but the first 10-12 hours of run time is most crucial to your engines' long-term life. So, order, install and enjoy!
