It's slow here on the drive-thru window right now, so I figured I'd post another topic...maybe we can get the "6 Cylinder" page 1 (BTW, the ONLY page) to increment to page 2! I have a woeful lack of knowledge about 6 cylinder Chevys and am curious if anyone on here has upgraded their 230 to a 250 (the so-called "mountain motor 6"). It appears the only thing necessary to accomplish this is swapping the crank and rods...is this so...are the pistons the same? And if anyone has done this, was there much of a difference in performance? The original owner of my car was a then 46 yr-old divorced woman who wanted her new Camaro to LOOK exciting, but not ACT exciting. She ordered it in Tripoli Turquoise with the RS option and a D90 sport stripe. Oh wait, a car just pulled up to the drive-thru window...
