The quality of the casting is good, the hardware they supply is crappy. You can buy them bare and have somebody knowledgable set them up, or just buy them set-up from Bernard Mondello, or CutlassEFI who is a member here. I've been running them for 5-6 years and I have put about 30k miles on the engine without any issues.

I wonder if it has something to do where it's measured on Olds, above the timing cover. Not the ideal place IMO.
On another note, I do need to talk to you regarding the BBC for my Chevelle. I've been following your builds for few years now, and they are impressive.

Thanks for the nice comment. I modify the oil pan so as RPM goes up, oil pressure goes up. I also have total control over all clearances. Example of a Olds 455 we clearanced among other things in my shop, with the correct oil pan.
