Thanks for the compliments. The resonators are from Stainless Works. The catch can is for the vacuum pump - actually the oem air pump that was converted to a vacuum pump.... that's not pulling any vacuum. Likes always said about the oem pumps - they don't last as vacuum pumps.

Thanks for posting the build-up. I've got a few questions:

Is there a trap-door in the oil pan to allow the oil that collects in the front of the pan to drain to the sump?

Whose cam are you running and what is the LSA spec?

What rocker ratio?

Thanks for sharing.

Jake
