T faith this is why if u look in the sponsor spotlight I called registered user out to a build off or whatever ,he can name build dynamics even if he wanted to just port a set of cylinders and send them to someone to dyno I'm in or do a whole motor. I have a hard time with someone speaking in a gospel type manor about engine porting especially with no proof . Hey he might make more power than me . I wanted to do a documented build like press crank together yourself since he is rod expert should be no biggie , limit port duration numbers so technique comes into play , stock head or cool head either will work for me ship it to be dynoed I'm sure a site sponsor would hook us up . Now I'm no expert on porting or theory or rods but I'm willing to stick my neck out .
