I'd install your rod/main bearings & mike them & give that dimention to the crank grinder so he he can grind the exact clearances that you are after.

---

Do you mean the old bearings? They are long gone.
And if you are referring to the new bearings, how do I determine which to get as I have no idea on how much needs to be machined?
This is where I want to start pulling my hair out!!

You would want to take in the block/rods also & they will 1st mike the crank rod/main journals & see what undersize bearings are needed & you & him decide what TYPE of bearings you need for your app (full groove/half groove premium or cheap etc) then he will order them & mockup the new main bearings in the block & measure the ID so the crank dia can be ground the exact dia to get your desired clearance on the mains. Same with the rods, they will in most cases need to be resized on the big end then mocked up with the proper undersize bearings depending on how much the rod journals need to be ground & the ID measured same as the mains then the rod journals ground accordingly. No need to pull your hair out (yet ),we got you covered.

What type bearing would I need? What dictates
a full groove over a 1/2 groove. RPM, how tight clearances being ran?
How much of a oil clearance do I want to run on the mains/Rod journals? Does determining if I want to run a high volume oil pump come into play at this stage? Do I need a HV oil pump??
Again this is a learning experince for me, I have lots of ??????

This is a free site, fire away. Std vol pump. More info on your intended use. I'm going w .002 rods/mains & maybe a hair less but its going to be a daily driver with only a little bit of stoplight action depending on how much attitude other drivers give me about the appearance of my beat up 65 Dart

450-500 HP weekend warrior. No drag strip, I doubt it will see 6500 RPM's. Want to build a respectable motor and not have to worry about a 5.0 Rustang or Honda cleaning my clock!!
I have a game plan on the build itself which I will post in a day or two when I have more time to sit at the puter and answer and ask questions.
If ya need anymore info on the use ask away..
Thnx Chuck

I know it will need turned as the rod journals (not the mains) have rust on them.

---

How rusty are they?? If its just surface rust I would think it could be cleaned up with with minimal turning or even a good polishing. I've seen it done with emery cloth, then crocus cloth. If its a heavy powdery rust, then yeah, minimal turning; .010 or less should work. If its pitted flaky rust, Just MHO

When they mike the mains I am assuming they will need the bolts and torque to spec. Shall I take my old set or the new? (bolts)
