Good luck. Looks like you have a nice combo.

Thanks!

Cranked it up for a few seconds tonight! Since I replaced the lifters but re - used the old cam, should I still do the cam break in proceedure? I did go ahead and throw some zinc additive in the oil.

YES!

Thanks silver. That's what I gathered from some google-fu. Just wanted to confirm.

Got it running and broken in. Had some pinging on drive home. I had been running a custom 93 octane tune from the previous build that had some advanced timing. I pulled the 93 octane tune and returned it to stock. The fuel has been sitting in the tank since about August, too.
