Mike, here is a video of a buddy's car back in Alaska. Video is from a couple of years ago, a couple of races after this pass, a secondary timing chain broke and trashed the motor. He had a Kenny Bell on the stock longblock, I think he was running VP109 and spinning the blower hard. It went thru a couple of axle shafts every summer.

He just got it running again, with bigger cams & a few other upgrades. Won't find out how it does until this summer.
Congrats on the blower upgrade, it really wakes em up.
