Hi, gang -
I recently was able to buy a *brand new* (NOS) BMC A-Series engine - it had
been sitting for many years in the corner of a race-builder's shop. He's an
old friend of mine, and he and had planned to use this mill for a race
engine but never got around to it, but now that he's retiring, he's clearing
out all his stuff.
The Engine Number is 8G150-RS54795, and on top is a 12G295 head. The bores
match that of a standard 1098cc BMC (it has the familiar "1100" tag riveted
on the side), and it has 2" mains like a "10CC" motor. The fuel pump flange
has never been drilled through, and it has one mounting stud installed on
that flange, presumably for securing the tappet cover's vent tube, as on
Morris Minors.
Strangely, the block has unusually thick (high) flanges on the sump mounting
area (about 3/8-1/2" high), and another odd thing is that the head does not
have any recesses in-between the ports (the 'pockets' that are usually found
above and below/ in-between each port are missing).. instead, the head has a
very wide, flat gasket surface area covering the entire exhaust/ intake side
of the head.
I have *no* idea what this engine is. The "8G" engine number would lead me
to believe it's an 850, but the bores are too big and the tag says 1100.
I'm stumped.
Can anyone tell me identify this motor? Is it possibly an 1100cc BMC GPO
motor? Or a BMC marine engine? Help! (please?)
Cheers,
Kevin McLemore
