1970 cadillac
Im looking for any info on an oil pump upgrade. Im looking to turn approx 6k on a 472 with hyper kb pistons (9.8 : 1) on forged rods with a .555 lift, 280 duration flat tappet isky cam & shaft roller rockers.
I plan to run a bit more than stock claerace on the rod and main bearings so im looking for an upgrade to the oil pump.
I can only find the stock pump from melling.
Im not above running a second pump if thats the way to go. Im sure that im not the first person to be looking for this answer so please point me in the direction of any solutions,,,,,
Thank you

Make .875 id tubing pickup tube. Wolffe air craft has mandrel bent 1 inch od .0625 wall. Make sump pick from 3 inch exhaust tubing. Use .125 hole pickup sump screen. Set pump gears to gasket used on installation. Contour engine block oil hole to flow oil into oil pump gears. Ball rotary file the 90 degree passage on engine into oil pump. Make adjustable oil pressure screw on side of oil pump where pipe plug is over pressure spring. Set oil pressure at pump to 100psi. Install remote oil pressure relief valve at oil guage port at rear of engine block as thats the last port location that receives oil pressure at the end of oil flow path. Vent the pressure valve into valley area of engine. Make 8 quart oil pan. Get oil away from that crankshaft. Or leave it stock and drive it to BINGO!

Canton products makes a 1.250 pickup tube for LS engines modified for competition. Thats 1.125 id at .0626 wall thickness. The LS has a long tube like the cad500.
