Re: Low oil pressure in ZL-1
Is this a new ZL-1 Chevy block 053 casting? it does use a relief valve under the oil filter. Make sure is was installed and staked in the correct hole as there are 2 holes it fits in. If not there, could be your problem.

Re: Low oil pressure in ZL-1
Remove your oil filter and look at the block. There are 2 large (3/4"?) holes. 1 large hole should have a check valve in it or you will bleed pressure like crazy. The valve is availible thru Chevy Performance Parts-Scoggin Dickey knows what it is if you tell them its for ZL-1 block.
