Tom,
I read on the Crane Cams web site that the company does not recommend the use of high volume
oil pumps with their cams. This is because of the greater risk of dist. gear failure.
This seems strange to me, since 90% of performance engines that would have a Crane cam would also have the HV pump.
I know mine has a Melling HV pump in it. I also have a new stock pump handy. I am wondering what I should do.
What type of pump do you have?
