[youngcorsakeenan]

Just wondering are all the 1400 ohc block the same? eg carb, spi, mpi
Are the pistons the same??

[Adam]

No

[youngcorsakeenan]

which ones are diferent? and what are the differences?

[Adam]

Mpi is different. Its the pistons that are different iirc, to give different CR

[youngcorsakeenan]

**** ok now i have to measure the CR of a spi block with daewoo head.

[jimbob-mcgrew]

normally in standard vauxhall form the carb and spi are 'N' ratio, i forget the exact figures, maybe 9 - 9.5:1 ? with a daewoo head on it tho, ppftt, could be higher or lower.

[youngcorsakeenan]

ye its hard to know and to important to guess, i have already measured the chamber volume and its 37cc.
