i mean the small end and there are many sizes.do the standard ones need honing and is it just a matter of pressing them in.most get oversize and hone them.some are thick and need to be reamed others just light honed.they also come in various lenghts which is not that importain.

If you’re talking wrist pin bushings, then replacements will be oversize on the O.D. and undersize on the I.D. Proper installation within the connecting rod bored hole requires a special swedging tool or mandrel that forces the bushing into the rough tooling left from the original boring of the hole. By design, the holes are bored to a rough finish so that the bushings can be pressure forced into the rough tooling marks thus preventing the freshly installed bushings from working loose during the long haul. Once the bushings are swedged in place, then the bushings are honed to a size usually based on an actual wrist pin measurement.
If the bushings are not swedged in place, they will eventually work their way back out of the rods. I recently tore down a Y that had had the wrist pin bushings replaced but not swedged and seven of the eight had worked themselves loose. Many shops are not aware of the special procedures required to properly replace wrist pin bushings in the rods which ultimately creates a situation where the engines must be torn down again within a few thousand miles. Just long enough to be out of warranty for many shops.

My preference when getting new wrist pin bushings is to get the ones that do not have the oil holes already in them. Having no hole predrilled into the bushing makes it easier to swedge the bushings in place. Depending upon the supplier, the bushings without the holes are not always available. The oil holes are easily added during the honing process and the drilling of the oil holes in the bushings after the fact insures that they are aligned perfectly with the already existing oil holes in the wrist pin end of the connecting rod.

Most manufacturers list different bushings for the C1TE and C2AE rods compared to the earlier EBU and ECZ rods. There is so little difference it seems a waste of time to me. I like the Federal Mogul/Sealed Power 1834V bushing.
It is doubtful you need any special sized bushings.
