Hi folks I've got a 1400cc block with some omega pistons in there is 74s stampped in to the top.

What cc is the dish on these postons ?

Thanks in advance

74 will relate to the bore, 74mm,

You'll need to measure them.

I understand stand the bore size. It the s bit I'm more interested in.

if this is in the block that youve had up for sale I suspect the S is for short so pistons intended for longer rods or a stroked crank, which would be why the pistons are sat down the block at TDC.
