Sounds awesome.

In regards to the pan, that appears to be the diamond scraper like the 20408 pan I use. I can tell you, Mark trimmed it out for the GM windage tray which is mounted off the studs. I’ve read people theorize that the high speed oil sees the diamond as solid, and the oil still splashes. Need a window to look through to see what may be happening.

Thanks.

I also have a Moroso 21017 that has better oil control, but it would not fit with my stock front chassis. I could have dyno tested with the better pan, but I wanted results with the pan to be used in the car.

No vacuum pump. Here’s the 1 7/8 primary headers with 3 1/2 collectors, and crankcase evac hoses, that will be bolted on in the car. I would have liked to dyno test the engine with these, but they were still in the car on another engine at that time.

I’m currently waiting on a custom built, bolt together, torque converter from ProTorque. While I’m waiting, I’ll swap out the MW 28/35, 5.29 third member with a Strange 35/35, 4.57. Trying to get ready for a track rental test and tune, and competition on the same weekend next month.

Why are you doing a bolt together?

Simple answer... ease of maintenance and tunability, while minimizing shipping and service costs.
