So it should since the A12 was little more than a stroked A10. The main changes were a raised deck block to accomodate the additional 11mm of stroke, & an additional two main bearings. Provision was also made for drawing out the crankcase fumes from left side rear of the block into the PCV valve.

The A10 was an almost perfect design for its intended purpose & the inclusion of the PCV system that was incorporated into the later engines would have seen 'perfection achieved'. Because of the very short stroke [59mm] & large crank journals for an engine of this size, the 3 bearing crank was amazingly stiff, so an extra 2 main bearings would have added only to the cost, the complexity, & the internal drag, but not to performance or reliability.

That front pulley is of great interest to me.
