Back here again.....
Ive emailed comp cams to ask that question but as yet they have not responded, time to ask again I think! I did a bit more working out yesterday and woulnd up with between 9.5 & 10:1 using the KB pistons (cant remeber exactly thats why the range!) they also figured dynamic compression to be around 7:1?!?
Cheers
Andy

Cam and CR need to be matched.
BTW, 9.5 :1 with iron heads is "safe" for Uk fuel, 10.5 :1 with ally heads. Just a rule of thumb, there are other factors.
