with a rotary. I can buy the full motor minus intake and exhuast manis for like 1300 I think. A fully built z motor with alot of porting, upgraded apex seals and whatnut runs about 3400. Thats dirt cheap if you compare that to building a z motor. Plus parts are alot cheaper, and they are easy as hell to work on. I found a 7 real cheap with a blown motor, was thinking of buying it and throwing a new motor in it.
