The same brand engines, that's the point.
Btw under your watch, foreman. You watched. I have machined and assembled a lot of motor, ported the heads... how many have you personally machined and assembled? Every engineer I have met always comes off holier than thou, you dont disappoint.
A machine shop see's a ton more than an assembly line of one motor company. Repairs ,modifications...so many variables unique to the designs from the manufacturer. How you don't accept any truth is amazing. You ignore all fact. You dont know ****...so
do me a favor and dont even address me anymore. Tired of your lame ****. waste of my time.
