Thats pretty impressive, my motor (still...!!) is having similar work done, stage 2 head, 264 piper cams, flowed inlet so am hoping for some nice gains, once I finally get it back.
Is there some sort of running in procedure that needs to be done after this sort of work as it seems you took yours on a power run straight after having the work done......??
Also, how different did it perform on the road from the way it was previously set up.....??
Cheers
