How to measure MAIN bearing oil clearance for ANY engine. Pontiac short block re-build, Part 4

Rod Bearings are done. Now it's time to measure and Blue Print our Main Bearing Oil Clearance. (What Not to Do, starts at the 10:00 mark) This is something you have to be aware of when building your short block. It doesn't matter what engine you have, it's the same process. If you missed it, check out the tear down episode... the bearings were toast! In this episode, "How to measure MAIN bearing oil clearance for ANY engine. Pontiac short block re-build, Part 4" We get to measure and blue print our dimensions for oil clearance, and compare my measurements with a professional engine builders results. In this case, the Engine Builder was WRONG! Lots to learn in this one. Including how to use a bore dial gauge (or dial bore gauge), and micrometers. Again, a big thank you to David Butler ‪@butlerperformancepontiac‬ for coaching me through what bearings to get, and what clearance targets to shoot for. If you want it done right, get your entire rotating assembly, and/or short block from www.butlerperformance.com Follow along with the Pontiac 400 (Now a 470) engine build, by subscribing below;
