where to find a guide for installing rods/pistons/crank??
Thats enigine builder know how. You have to either read a book or go to school for it. Contact a few sponsors on here and see if they'll help you out or buy a book on engine building. You can look for online guides but that info usually isn't free.
It needs to be done right and shouldn't be done by an amateur from an online guide. You also dont have the tools, if you had the tools you'd have the know how. Clearances, knowing tolerances and application. It cost money to go to school to become a competent builder, or years of experience as an apprentice in a shop.
