93 Cobra needs input · 03-21-2002, 07:21 PM

Just trying to clear up a little confusion that may have been spread on my post. I have purchased a new 331 kit from Keith Craft racing and the piston pin goes right through the lower oil ring on the JE dished pistons and the block needs to be clearanced for the larger rod size. It sounds normal to have these issues even with the 331. The rod ratio is a lot better than the 347 and there are no oil control problems. Just thought I would pass along the info.
