if i had choice between 1200 and 1300 id pick 1200, its got a shorter stroke, and all the 1300 ancillaries can fit on the 1200 as i did once, e.g. skimmed 1300sr head, twin down pipe doesnt mean 1300, some one could have changed it, its not very hard to do!
thats just my oppinion anyways

I just wanted rid off the spi in favour of carb, and it seemed a shame to leave it lying in garage, i needed a quick increase in power(if only 20bhp or so) and cheap as the car's only gonna be out for 2 more months before being stripped down over winter. The new engine is a big improvement over spi, it rev's far better and it has more power higher up the rev range, unlike the spi which seemed to have same power at 2500 and 5000rpm. I am thinking of keeping this engine after the nova is rebuilt only tunned to keep her light.
