Per Jon Kaase racing engines I used a melling hv pump and valvoline racing oil 20-50. This is a new pump replacing a new pump. I dread checking the rod and main bearing clearances but I am about out of options (man, this sux). You guys have all been great for responding. Let me know if you come up with anything else. I'll keep you posted.
I did not change the spring in the pump but achieved higher pressure with the replacement. I also have not checked pressure at the oil galleys-I have only checked at the back of the block. This is the ford racing A-460 block and I am new to the ford thing. (been a chevy guy all my life, I just have a mustang fetish, he he)
