Thanks Steve, appreciate the feedback, and yes I will verify how much advance I have. Unfortunately I won't be able to work on the car until this weekend due to an out of town trip but I still have the same question. This blistering occured during the initial start-up on the car under idle conditions while checking for leaks, cooling fan operation, etc. This did not occur from driving. It never left the hoist.

The builder told me that they verified on their hot run 36 degrees at 2500 rpm. I will make a post this Saturday after I put the light on it again. Many thanks!
