Need A Little help Please

Should be part number 40200914, or some variation of it.

I’m pretty sure those are some Ultra-
Dyne lobes that Harold Brookshire brought over to Lunati when he was there designing the VooDoo stuff for them.
That family of lobes is pretty aggressive, so they tend to act a little bigger than they look on paper.

Do a cranking compression test.
You’d really like to be in the 200psi range.
