OK, I am getting ready to install a dry sump system on my 615 with a dart big M block. Question I have is do I just need to remove the old oil pump and install a block off plate where pump mounts on main cap? I couldnt find any info looking around online. Thanks

Here you go... You putting a primer on it too?

I bought one of those alreadything that was all I would have to do. Good deal. And I will pull belt and use my drill like I do on my dragster dry sump

Tap the hole in the cap for a .15 1/4 npt plug. done.

This is a running engine so I will use the cap its not feasible to tap it right now. Thanks guys
