Thanks guys.

I pressurized the system with 20 psi, buy bypassing the radiator (plugging off at top and bottom of water pump) and putting an inlet at the T-stat housing. It held fine. I went ahead and pulled the pan to clean the screen, check the status of the oil pump for specs.

I've read somewhere once before, and not cannot find it, that there is someone who makes a more modern type oil line kit to run thru the block. Can someone fill me in on if they are still available?

Thanks
Chris
