Appreciate any advice here.
The original plan was to drive the dry-sump pump from a pulley behind the crankshaft pulley. However, a 4 stage pump will not fit here with a DSE subframe...without significant modification to the crossmember, engine mounts and the exhaust. Significant is an understatement.

Aviaid has suggested this drive pulley which would mount on the front of the crankshaft pulley which would pull the pump forward. It doesn't completely solve the problem but makes the modification manageable. It will require that I build a custom mount for the pump but it seems doable.

The fear with some I've spoken to is the torque on the crank, bearings and the pulley with this hanging off the front.

Though some think it's no problem.

DSE doesn't know of anyone running an LS7 with an external dry sump pump with their subframe.

Appreciate opinions and any advice.
