thanks whiteAP1 now i know to stay away - ive pretty much found some better places anyhows,

TODA..

so u recommend staying 9.5:1, thats what many in the states run, although it as u would be aware its hard to see what cp the big teams run on their car, i had a suggestion made that the cp bump up to around the mid 10's - Which i was a bit worried for a big hp motor (this is gonna be a special motor with lots of research)

well overall the dart tall deck will be a definate but is it possible to make one to 84mm instead of 84.5? they come around high 83 untouched from the factory. just if i need to rebuild i can then go out to 84.5.
