plug the stock pickup hole & go with an external static pickup & pump cover like my earlier pic. excuse the metric sizing but that's what we have down here, 1/2" stock pickup is only 12mm dia, the single static pickup is 16mm dia, that's 25% larger plus there's no sharp 90* turns inside the block restricting the oil flow. I'm using this single static pickup on a 750HP engine & my bearings(clevites. not speedpro) look almost good enough to reuse again @ engine freshening time.
