Been wondering which oil pump to run std. or HV. I have a 451 with full groove mains and .00225 clearance on the rod and main bearings. I have the oil galley's reamed with 1/2 oil pickup. Going the hemi oil pan route that fits a body. Would normally run the HV oil pump but was concerned about premature wear on the distributor gear? This would be if I went bronze. I am also wondering about the other distributor gear alternatives.
The cam is comp cams XR 280.
440 source rotating assembly
Edelbrock rpm heads
comp cams roller rockers
The car is manual trans and will be mostly street. Any input or experiences would be appreciated.
