Looking at recommendations for replacement oil pump. The advice I had is from back in the day and was to use a high volume. Engine is a 440, 0.030 over. 12:1 CR with TRW pistons. Main bearings are half groove. Cam tops out at 6000 rpm. Have 8 quart pan for it. I have had high volume pumps on engines in the past with no ill effects. I am just not sure what the current thinking is now days. Any recommendations on a pump?

Morning Tim, alot of variables go into it, bottom line is to use the thinnest oil/std vol & psi pump that will maintain a safe PSI for your eng/app. Idle can actually b low if it jumps up right when you goose it and on the high end for a dragger 8-10 psi per 1000 rpm is a safe ballpark figure. I'd b way more concerned w doing the proper internal mods rather than what the gauge shows at it's highest point when it exits the filter & goes up to the sending unit

Just curious, would a standard pump be ok for full groove main bearings? Thanks
Generally yes with typical clearances and oiling.
