Xs power have moved on leaps and bounds over past 5 years, Old style suffered with 2 piece castings breaking at seams,ill balanced componants aswell as not the best spec wise, castings were of poor quality meaning to weak theads on bolts holes etc. Recently there has been large investment in the company as a whole (takeover??) The qualilty now is MUCH better, 1 piece casting, hi quality casting/material and tolerances have been narrowed to a high standard.. Still not always ideal specs but not bad on most units. The need of 360 bearings still needs attending to as most units application exceeds the standard bearing limits.

I would happily run (and have seen run) on stage 3 cos maybe up to 400bhp without a care in the world.

Re go with a rebuild T34........ How do you know where the parts for it came from??
