Ok guys, I'm at a loss & need some help! 2.3 ford. I bought a running, race winning, short block with aprox 6 races. I checked it over before installing & all looked new. I bought an already worked head, but had it checked over, & changed the cam & springs. this is a non roller. Cold oil pressure is 40. after running the cam brake in for 30 minutes, & dropped the idle speed to 1500 rpms, it dropped to 15!! The cam bearings are not slotted. I noticed that the 2 center cam towers were drilled & tapped but were not capped. I capped them off but only gained a couple pounds of pressure. I was running a remote oil filter & even unhooked it & put a filter back on the block. Any Ideas? Thanks for any help or ideas you may have. F-9
