After getting my MGB 5-main engine back from the machine shop for my ‘74 MGBGT Autocrosser, there was a delay while waiting for the last bits to be able to start final assembly.
We finally have those bits, and the engine is going together. In this video I will be putting the crankshaft in and setting up the end float so that we have a nice freely rotating engine and tell a cautionary tale of assumptions and lack of knowledge that cost a previous customer an engine. This is the first of 4 videos on assembling the short block, look for the rest of the videos coming up once a week.
