I know this is from February, but I have some input. My lower control arm bushings were replaced about 8 years ago. The car has been down for repairs since 2020. I looked at my lower control arm bushings, and they were split open. Moog brand.
Hey, I live in Weeki Wachee!
Your post tells me what I needed. I was wondering if a high pressure pump would make a difference. I brought up the idle a little, reset timing. It seems good.
I don't know what the bearing clearances are. I had the machine shop assemble the rotating assembly. Nor does the 440 source website mention whether or not the bearings are grooved. If I idled at 1200, then it would be at a more reasonable pressure.
I agree. I would be happier with a little more. I will try changing the oil, and then try idle speed, and timing. Then, if I feel the need, I will try a different pump.
So, my question is still
Are there any pumps that put out better pressure at idle than the generic high volume pump.?
Do hydraulic roller lifters cause lower pressure? (Howard's brand).
Wow, what a great explanation. I already have 20w-50 oil in it. i would be happier if it had another 5 psi. Thanks for taking the time to explain all that.
I don't know what the bearing clearances are. It was a 440 source kit that was built in 2020.the shop that built the short block is gone. I will go to the 440 source website, and see what type of bearings they gave with the kit.
The Borgeson box needs the higher pressure. I would take the shim out, and ask where you bought it what you can do. I had some problems, and Peter Bergman helped me sort it out.
Guys, I have a 505 stroker that is all new. Roller cam, Indy heads.
When my engine gets warm, around 190*, the pressure drops below 20 psi at around 800 rpm. This is the same thing that it did with the old 440. I used this pump because it was new. So, I need an oil pump that has higher output...
I bought a Summit timing set, and the crank gear has some play when on the crankshaft. just enough movement so you'd notice. Aren't they supposed to be a snug fit?
If so, I was going to replace it. So, for a 505 inch stroker, what brand would you choose Rollmaster, or Cloyes? It's a 3 bolt cam...
