Run a Melling HV pump add the pump cover and go with a swinging pickup...The stock style HV pump will feed 99.9% of most engines on this board in this fashion..
I have personally turned a 560 CID big block 8K no problems...
Chuck at Best Machine said they will feed to 10K.
No green gasket to blow. I run aftermarket blocks, and I plum one line from the oil port by the timing chain cover on these Indy Maxx blocks, and the World blocks...For duel line setups, this would be one, and from the pump cover bac to the pickup is the other.
