Re: Who's Running the Super Rat?
I think you have a GT5A jug. It has a 40mm intake spacing but is 1mm shorter than the GT5SR Super Rats jug. I seem to have read that there is a crank with 115mm rod length, I think it was Dax. My 38mm GT5 type engine has a 114mm rod and uses the high pin piston. If what I am thinking is true a GT5A jug on a Dax 40mm bottom end would having a piston that is 2mm proud of the cylinder. Or I could be totally wrong!!?
