1.)Wrong sub-forum.

2.)Nobody here can answer this question for you. You will have to take the engine apart and measure the rod journals and big end bore to figure out what you need. If it's a virgin crank, you will likely need standard bearings but you won't know until you measure.

 

Depends on what you want to do with the engine itself and what clearances you'll want or need for that purpose; boost? N/A? Race? Daily driver? Daily driver with light track use, i.e. mixed use? Too many considerations to narrow down an answer for ya right off the bat..

 

 

You can use standard bearings as a start, I am running skunk2 alpha rods and am using clevite standard bearings, for instance. Depending on the condition of your crank journals, you **may** need to mix and match sizes though to hit your desired clearances. For instance, let's say you want .0015 clearance. You **might** need one set to be a standard and oversize. It's a crapshoot at best. You can easily overthink and underthink the situation entirely. One thing to do is order a set of standards and see where you're at when the smoke clears. Install those and check your clearances and see if that worked or if you need to order additional sizes.
If money isn't a concern, order one set of each; standard, under, over. Clevite standards put me at a perfect .0015 on all rods, BUT, that's also my particular situation. Methinks I just got lucky lol!

 

 

Now you've opened Pandora's box.. What noise? What rods and pistons? Know any other info about the build? Ring gap specs, piston to wall clearances, cylinders and/or girdle notched, etc? You may have a simple issue, or a big one. Might be normal, could be catastrophic. Need more info though lol!
