When I rebuilt my motor agian{dropped the pickup spinning a rod bearing} I got rid of the Meling HV pump with the stock pan{sucking the pan dry at Wot causing a 10 psi drop in pressure} and went back to a LT1 standard volume pump with a high pressure spring{White}. Cold the car idles at 70psi. Warm it idles at 22-25 psi with an 850-900 rpm idle. Above 2500 rpms it runs 62-65 psi. Much happier with the results.
