Just a quick question/note. Regarding the HVHP pumps, I had a respected IMSA engine builder here in Illinois (Protech Engines in Mokena, Illinois) tell me to watch the HVHP pump on a 400 HP 2.3 turbo. His reason was that there is a pretty good chance of washing the cam bearings. I thought he was a little over-cautious. Well, I didn't listen and used a HVHP oil pump on the 2.3 turbo and on a really healthy 2.3 carbed engine that both saw a good deal of street driving. After a while I noticed that the oil pressure started to drop off from what it had been. I tore the engines down and sure enough the cam bearings were "washed." The bearings were Cleveite (SP?) and the cam was a Ford Motorsport roller cam and the cam towers were well within specifications. Soooo, after that little incident I've been a little hesitant to use HVHP pumps unless the engine is going to see strictly track time only. I understand that 2.3 Fords are nothing like FE big blocks but I'm not sure if the HVHP pump had anything to do with the bearing failures. Now, before I start my first FE build I'd appreciate any engine builders like KC, Berry R, etc. weighing in on this. Finally, I apologize for getting this thread side-tracked.
Thanks in advance for any and all thoughts on this!
