2.2 bore spacing

[richard.b]

Hi there,

Does anyone have a number for the bore spacing on the 2.2 motors? I've found references to it being the "same as" Vauxhall and a few others, but no actual measurements. Anyone got some hard data?

Cheers,
Richard.

Try talking to your local engine reconditioner. They have books of engine specs available for a widde range of motors.

Thanks Rik. 4.250" it is then. Same as 907 motor I presume?
