I recognize a TON of the things done inside and it's definitely not stock! I believe Winners Circle may have been the builder. Winners Circle's engine builder passed away a number of years ago so I have no person to explain the mods to do that can be verified.</div><div>I wanted to find out the main & rod bearing sizes . So I popped off a rod cap and a main cap to read the bearings. No bearing size stamped on the back side of the bearings. VP's logo is clearly there and numbers on either end of the shells but not one indication as to the bearing being standard or undersized.</div><div>The rod bearing is stamped 2783 on one end which is a BMC A series rod bearing general shell number. The other end is stamped 2A 690. That's it!</div><div>Main bearing has 4105 on one end & AEA 308 on the other end. </div><div>Now! I simply pulled 2 bearing caps simply to see what they looked like and find sizes so if I thought it needed fresh bearings , it would get them. The main bearings looks brand new with no run time. Rod bearing looks like possibly 1 race if that. The stuff in this motor looks like the motor was built 6 months to a year ago! Outside looks like it's been sitting around for 30+ years. Block was painted black. Cylinder head ( with Champion N9Y plugs) was never painted. </div><div>Since this motor looks very much like it has a "red" crankshaft in it along with all the period hardware. </div><div>Trying to keep it from hurting itself ...if I fire it up.....</div><div>Chuck</div></div></body></html>
