okay 87 5.0 new melling high volume oil pump new motor the deal is the old one got some pencil lead piece of hard steel in the pump gear i changed it out had to drive the car home put a mechanical gauge in it sun pro ( buy a good gauge the sun-pro sucks it sticks maybe just mine but anyways vdo best way out) it twisted the pump shaft twice i bought one and it did it in the drive way in five seconds. what would be a motor with say 1800 miles on it oil pressure its bore .40 over e-303. also it does 60lbs. at start up and between 50 to 45 and some 40 when i get into it i get almost seventy out of her should i be worried about the journals or what i need some council on the lower end of the motor i know the whole ten pounds per thousand im looking for some good gear head answers here ladies guys

the hot rod in question

FoxGT

Not sure about getting up to 70...
I took my high volume out after I rebuilt my bottom end... I get about 45psi at idle, which is about 400-450rpm (x303 cam) about 55psi while cruising & 60 at higher rpm... All of these #'s are while it's at operating temp.

I have about... 3000 miles on the rebuild, replaced the crank with a used one ground .010 / .010 on rod/main. replaced rod/main/cam bearings.

Hope that helps....

sounds like whoever build the motor didnt inspect the pick-up tube for debris, and its locking up your pump

Puncuation man,lol. I'm getting to old and confused to read a sentence that long. I have 65 at cold idle and around 35-40 at warm idle.

dumb question but what weight of oil are you using??? and 45 is normal for idle 50-60 when ur running it hard
the motor requires 10 per 1000 rpm which u already no but at idle with a mild build you should rock about 45

to day i was running her pretty good and when i stopped it was at about 35 at a redlight, when im on the highway she does about 53+. and when im setting in the drive way i get the 10 per thousand. keep in mind that this motor has 1372 miles on her it was a new pickup tube. im running 10-40 but switching to 20-50 today. im in south florida so it always hotter than #alls down here and im gonna run lucas as an additive.

Alot of folk's will disagree with me on this. I live in GA and use 5 qt of 20/50, 2 qt of 10/40 and a quart of lucas.

you live in S. FL--- and man i live in NW FL--- i just recently swapped over to Royal Purple 10w 30..... and ya'll are talking about the idle/ oil pres. density... At idle (warm) i'm at 35'ish and cold idle i'm at like 45'ish.... When i get on it, it shoots up to 60... And i use 7qt's + Lucas oil stabilizer and every 3 oil changes (which a oil change a yr with much as i drive it) i add Restore....

10k miles ago when the motor was being built (just mods listed below)... the mechanic was like "damn,,,, motor looks clean". thought that was funny

My motor runs on 5w20... and woody wants me to run 0w20 synthetic in it
