Allow to me rephrase: avoid maxing out the RPM's until properly broken in. At the same time you do not want to lug the engine at low RPM which will glaze the cylinder walls.

What I did with my new engine (and the engine I built with a f'd up reground cam) was a nice long highway drive with varying RPM range between 2500-4000 RPM's

Did my oil changes at 100, 500, and 1000 miles then the next at 4500 miles. After I hit 10K in another month or so I will go back to synthetic oil.

 

Oriellys brand 5-30 is what I use, have been using 5-30 since Ive had the trucks.

 

i always just run the cheap motor oil on a fresh motor. no point in buying the 6.50 a quart stuff when you need to change it within 100 mile of firing up a new motor. new motor as in bearing wise. IMO just pulling the fuel pump relay and turning over the motor to prime it does nothing. your starter only turns the motor over so fast that the oil pump doesn't even build enough pressure. i always just fire the motor off and hope for the best.

 

Yea started the install Sunday, was all bolted up. Then awwww crap! why won't this wire pull up? What the freak?!!

Yea had pinched the rear ground wire between the bellhousing and the block.
Well unbolt everything (dang bolts are hard to get to) pull the wire free. Bolt it all back up again.

So Monday got everything wired up, tidy'd up, cleaned up. And cranked it up last night.

Man it was a good feeling. Good oil pressure , about a needle width less than 40 at idle, and almost 60 when romped on.

Couple more things today like the skid plates, fender well, minor stuff. But its done and it runs good and quiet.

 

I killed my cam sensor connector between the enging and trans...

Its great to hear your work come to life! Seems like you should have more OP than that though.

 

ya i guess i forgot that didnt apply for rollers lol.

well like i said before then, give it hell from the start. change the oil after the first few hundred miles. then again by 3k. after that run some nice 100% synthetic and have fun.

 

I dont know. I thought that was pretty good pressure.

Even when this truck was brand new 11 years ago, it had around 40 for an average.

Could be just the gage reading like that, being electric and all.

May just tap that plate down by the oil filter housing and connect a mechanical gage just to see.

I'm just glad its running and has more than 'zero' for a reading. And its not fluctuating like it was before it died.

 

thats the same oil pressure i run on my stick 6.0 right about 39 to 40lbs at idle
