topcat 11 Report post Posted June 6, 2008 Hi Guys looking for info on the b35,flow info mainly. need the info to start to calculate the VE,compression stroke,cam timing etc. also to make some base numbers,before we start porting,stroking,headers etc. Next,who knows where to find springs,namely double valve spring setup for the b35 as its going back together soon. just had a 'trail' run with fitting larger exhaust valves.3mm larger at this stage. the standard exhuast valve basicly falls into the bored ports. looks awesome,hope the flow bench will also show good results. cheers,and yes will take some pic's etc-marty Quote Share this post Link to post Share on other sites
