Default Re: Who's Running the Super Rat?

Ok this is a slight head scratcher- While I had the Super Rat top end in front of me I went out to the Garage n grabbed a Dax Bottom-I know it's a long stroke motor bottom. Using the "super rat" piston incl. I assembled. At that point I rotated the crank -piston at TDC was about 1/8" above cyl then @ BDC all ports 2/3rds blocked . Using the long stroke pist would have exaggerated this descrep. or I suspect it would hit flywheel before bottoming out. I don't get it. The chart says a Super Rat is Long stroke, but obviously this top will not fit a long stroke motor. I must re-look at this whole thing again. I'll post as I get info.
Thanks Cannonball
