As a relative neophyte, I am wondering about the differences between these engines and the standard jetted ones. I know a few things. The blown engines used the mag crankcase and the unblown used coil crankcases. Blocks and heads were Chromidium. Were there water pumps on both blown and unblown? Valve adjustment by shims. I also know the feet are different from the jetted engines. Does that mean a blown or unblown Ulster engine won't fit on a standard chassis with a replica body? I have heard that the early engines(1930) used the same number of head and block studs as the jetted engines, but this increased over the years. Is this the case?
