thanks for the info. Useful for me too in some ways.
However, I want to convert from std 6 (202) to a 308, straight gas. Would i use the same considerations as u've described for the 253? i'm guessing i'd have to do something about the suspension as it's a lot heavier? and figuring the diff would need changing? not sure what's in there, Beigy is stock std so my guess is whatever they came out with. I'm also wanting to do the mild cam thingo, nothing too radical, just a good rythm and sound. I'd like to keep it a manual (currently 3 on tree), and am thinkg of going 4 or even 5 speed manual, but hav peeps telling me that I should go auto instead. Any ideas, advice? I'll be removing the petrol totally and putting in a second gas tank, the dizzy's going to be set up for gas too, as well as the heads and of course the cam. I don't understand a heap about modifying, so am fishing for info at the mo.
Will be grateful for any feedback.
thanks
