Just recently was "lucky" enough to find a set of main bearings to fit a -10/std/std crankshaft/case Type IV project. Already had a std/std/std set for another project (Kolbenschmidt brand from a WTB advertisement here in 914world.com).
However, most of the usual sources are currently out-of-stock of any brand main bearings. AAPistons.com has some silverline branded ones. Has anyone recently found any vendors with main bearings? If so, please share, so we all can know where to source main bearings. Thanks in advance. |

From what I have heard the few people (builders) that have a supply of GOOD bearings are holding on to them for customer builds so the current options are paying someone to build you a motor, or not building a motor.
