Correct, I do remember hereing a few things about the Oseries engine being
put into limited/random cars from 77 or so on to 80. But I also am pretty
sure that what Bruce Durgin had said about a 62 MGB twincam, is true...I
have also heard that. It isn't an MGB engine it is a leftover 1622
w/twincam head, and I don't know if it is a MGA gearbox or not.

I don't want to blow Miatas into the weeds, I was just wandering what
peoples opinions were if they could purchase an MGB twincam head, and what
complications might come about. I just think it would be a neat thing to
do because of the "coo" factor and it would still have an all MG
heritage...
