540 HRD
« on: January 24, 2013, 06:34:26 pm »
What makes a zilla motor a HRD? Thought it was one builder who made them but I am noticing on some post 540 hrd built by-500fanatic or MHR. I know the 540 is punching it out to a 88mm piston. Only reason i ask is supposedly I own one.

well sorta, yes its the 89.5, but they just go with the last bore and call it that.
i have a few and they range from 87.5, 88. but if you send a stock bore cylinder, after they weld and do work to it
then they have to bore it out cause all the work screws with the bore.

540 HRD is Q's version of a motor that can be used for racing and duning.   
Q shared his port specs with a few engine builders and allows them to do similar work and call it HRD.
That's why you will often see HRD mentioned with the engine builder name after it to clarify.
