stan lippert told me the type1s were all 360's i know my type1 cp77 is. im pretty sure the closest id for todds bikes were 1 3/8. i remember chris saying the actual id was something freakish and impossible to get. so 1 3/8" it was. todd built some fast shit, but he wasnt stupid chasing impossible things to get. plus people seem to forget how great of a rider her was. not only winning alot of vintage races, but also quite a few modern races back in the day. having kc do alot of work with you helps too!
hack, if you want alof of super tech answers, i can give you contact info for all of the best cb350 motor builders in the country. the people we send our stuff to. chris m oversaw the construction of my last motor, stan lippert did my head, and i was never fortunate enough to have todd do anything for me. but would have loved it. chris has his own pistons made, but even admits the science of it escapes him. his pistons are todd copies. if you could get the run number from one of those guys you could call wiseco and ask. generally, if youre running stock pistons, youre not allowed to really do anything to them, so they get tossed in the motor. bing bang done.
bore stroke and rod length should be in any decent book or paper, or easy enough to figure out with a few measurements. valve sizes i cant remember. but they are easy to find also. the big motors all have variable cam timing depending on comp. alot of guys run different head gaskets. so clearance becomes important. you basically have to have a slotted cam to keep things from exploding instantly. jb knows all this crap.
id like to know why no one makes stepped headers for these things??
