as topic suggests, i am curious as to the new cnc heads that are available from jim mock. Has anyone experienced the new heads or knows anything about them?? head work is the next step to my build but i am trying to decide which way to go! i am also keen on getting the solid rocker setup they also have available as the standard liftrs are having trouble keeping up with my cam as it is, any info on these would be appreciated aswell!

cheers

Just wondering has any one tryed these heads and if you have what sort of power gain did you get... I have a XG XR6 Ute sitting in the shed that's going to get a work over next year and have been looking at building a N/A engine.

While on the subject has any one bolted a big N/A engine together what did you use and what sort of HP/KW did you achieve...

I was looking at around 200+KW at the wheels N/A now this will just be a weekend warrior and strip vehicle just want to build something fun to drive. Had the Ute since new from 93....Also whats peoples thoughts on the Snork 1200 Ice man for N/A application.... Also want to go N/A don't want to go turbo or charger..

Has any one seen a Atomic N/A 6 taken to the edge....

Are you talking 200+Kw at the fly wheel or the wheels?

SOHC or DOHC?

Sorry, raptor. Not trying to hijack your thread. But want to answer blade's question.

Trav199 managed to get 246 rwkw out of an N/A DOHC:
