[QUOTE="Phil Davies, post: 84868, member: 2541"] I have seen that engine on the bench, I can tell you there is more alloy as weld in it than was in the original complete engine castings. Rumour has it that it was originally one of the ex Martin Davenport engines (as Dave M bought the original outfit and spares from Mart) The primary side crankcase mouths have been expanded externally in order to move the cylinder stud holes, the inlet and exhaust ports look nothing like a Vin product, the entire ex port being re-angled. The man that buyilt it for DM was a AMC G50 man, so he set about replicating as much of the G50 dimensions on to Vincent heads (personally I would have thought it would have been less trouble to cast new heads), the opportunity was also taken at the same time to bore and stroke it. The crank is nothing like a Vin crank - its oval, yes really! [/QUOTE]
