Oil pressure vs lifter pump up

Yes, oil pressure can help. A mentor of mine ran Stock Eliminator witha Ford 351 Cleveland. It was a hydraulic cam engine factory, so he had to keep it. But he ran 130psi oil pressure. The car set several NHRA national records that way. He'd drop the clutch at 6800, shifting at 7200. The car ran 11.teens witha 4sp. Also, the only oil filters he found that could withstand that pressure were OEM Ford. The others would pop the cans..lol. But, if you have sloppy lifter bores, a higher pressure may not be the fix. Poor geometry and spring choice and setup have a lot to do with valve float too.
