Actually it does seem that changing your pan and pick-up might help. What pan and pickup are you running and how does that compare with what others with 460s are running? (I have an FE, so can't really comment on what works, doesn't, but something to consider).

Thanks! This is some great information. We still havnt got to the bottom of it yet. My builder is in ohio and i am in ny to make it worse i have a broken leg. so i need help and other peoples time. Anyway we are eliminating the small stuff (crossed oil lines on remote filter, the filter itself, pressure guage) We cut the filter open to ensure that we didnt suck something into the pick up causing restriction.

I think this is coming to a head. We used a brand new pick up on this motor, first time he used this type of pick up. (this is the only change made from the original motor). I was suspect of the new pick up from the beginning. The Kaase post leads me further down that path. The original pick up broke off which caused my motor to blow. That is why it was changed with another. I will pass this info to my builder as the fix may be to change the pickup or the pan. The 8 QT canton that I have takes up every inch of space, not sure that it can handle a larger pan?? I dont know the exact style of pick up used.

Thanks again for the info, I will be sure to report back on the solution.
