we have been held up on driving the 68 because Of the base gasket for the carb is a 67-69 only. finally got one in need two for that car one on either side of the plate. it finally arrived and yesterday we got to drive the car around for a bit. man that thing gos good. the high compression engine has so much more power then the 70s version. it's unbelievable. all most as good as the Oldsmobile is. put it in the shop to get a new muffler and tailpipe on it so we don't blubber. just for reference here is the base gasket for those of you that have one of these cars.
