just a quick up-date on my "too high oil pressure" issue. i waited till thursday of this week to hear back from george (the tech at melling), who was going to send me a "speced" out pump so i could eliminate the pump as being the problem. points were supposed to start this weekend so i wanted to be at the track to race so i installed the used pump i took out during the freshing of the motor and the high oil pressure problem has dissappeared (as i thought it would) motor now shows 65 lbs @ idle and goes to 75 when rpms are increased. sure looks like my contingency winnings were 2 falty pumps. i still am of the opinion that they need to be made aware of these problems (by the masses), they may be in denial but hopefully they will fix this issue. that or who else makes oil pumps for small block mopes? 1 source said ray barton said melling does not make the mopar performance 1s, but mp quality issues don't let me sleep well at nite either lol. dave

***update***

I changed to 5W-30 and made 16 passes with the car. When I first fire it up it's up there around 85+ but when it warms up it is 65 at idle. Wide open throttle making a pass it's 80 and after a pass coming back on the return road it's 50. So for now, I'm gonna leave it.

dc: i'm using the partial syth. brad penn 10/30 so i don't think it caused the problem. also i checked the rod clearence while changing the pump and it was .017. my pressure with the 2nd new pump was over 100 lbs when revving the motor. i'll run the old pump but would like some options for the future. dave
