Hi to all members, just thought I would to see how many of you have incorporated the oil restrictor kit to all five cam bearings as George Pence has advised ,and how has the engine longevity been? Has anyone after the installation had to tear the engine apart for other reasons and had a chance to inspect the crank bearings after miles of use?
I can't decide whether to complete the mod or not. The engine builder here that is advising me and who has years of Cleveland drag racing experience says I should not do it and was not convinced when he saw my bronze lifter bushing installation. He told me that its a problem with the front oil passages from the pump to the oil galleries and connecting rod clearances that is the problem. He has been completing his own modifications to the oil passages for years on his own engines and for his customers and has never had a bearing failure.
So, now I don't know what to do.
George and Dan, I would love to hear from you on this topic and how many engines you have completed this modification on and bearing conditions after miles of use.
Thanks Mark
