Hello Datsun1200 members....1st post but very familiar with the site. I have come to the conclusion to transform my 72 MG Midget into a Japanese/British hybrid car. The A series engine is an excellent choice as suggested by many MG owners. I was directed to this site for expertise in rebuilding and identifying parts as I accumulate them. By reading numerous threads, I have definitely come to the right place and hope I get the help I need as I move along. My intentions are no more than 80-90 HP and a mild rebuild with twin carbs I picked up from an A12 motor. First order of business is fabricating motor mounts and other modifications to the chassis but want to get some engine information as the chassis work gets done so that it can go to a machine shop afterwards.
I have acquired an A15 engine from a 1982 B310 car (pic attached) which had about 200K miles and surprisingly the motor turned freely and the cylinders appear to be real good shape. Even the timing gears look to be in good condition. The H95 head will sit on the shelf and be replaced with a GX head (I think) from another purchase. Reading the 1200 tech data, it does appear to be the GX head. No numbers are stamped on top, only Japan Nissan. Also have the intake and exhaust manifold. This all came from a 1972 Coupe. My concern is that the engine does not have a dual point distributor. Is it a GX head?
My understanding is that the A series cylinder heads are interchangeable with the different blocks. I read on one of the threads that an oil passage hole has to be drilled if a GX head is used with the A15 block. Any information on this would be appreciated as well as camshaft modification and other rebuild advice. Can I use the lifters that were used with the H95 head? Enough said for now and will wait for replies and post more pictures later. Thanks.
