[Spridgets] BMC / Spridget parts identification

[Rick Fisk]

Ron and Chuck,

I could use a new race engine, but can't afford your 948.  Found a kinda sorta race car for sale on FB marketplace. It's a '77 Midget configured with a 948 as an HP racer. ??? Seller included a photo of a receipt for engine service from a Fond du Lac machine shop. Look at the very last item in the parts list.  "Parts from WST."  lol

>> The 12G295 head is indeed a 1098 head, it is also a good head to USE on a 948 as it has larger valves and the lower combustion chamber volume to start with, and it was used at some point on the 998 Cooper. This is one of the three preferred heads for a performance 948 as there is less work to be done to unshroud the valves.

>> A long time ago in a far away galaxy...( oops!? Wrong story!)Ok yes a long time ago I was deeply involved in the early days of what became the 55-57 Chevy craze.? Where this is going is I'm having difficulty decoding and understanding casting dates or codes and some contrary casting number aplication references in order to understand some of what I've required over the years.? ?In the general motors world every casting not only had a raised part number but also a casting date.? You knew you had a February 1955 intake manifold by the part number and the casting date.?Yesterday I found a 12G295 bare ( kinda rusty too!) Cylinder head in some forgotten stuff.One site states it's a 1100 MG head , another states it is a 998 Cooper head AND yet another states its a good 948 head without refrence to its original intended application be it a specific displacement motor OR a spread of ( start to end of use?) Application years .? ALSO I'm finding references to "home market" & " export market".?
>>  ?So it starts with a "12G" does that denote 1275 original application?? Is it indeed a 1098/1100 head ( I may need a 1098 head?) ?Im a lot behind in the decoding of these items.? I simply used what I had years ago..Thank you!!ChuckSent from my LG Mobile
