J12480 Posted February 3, 2005 Report Posted February 3, 2005 Now on fourth season of motor and wanted to upgrade. I'm going to split the case and have the crank welded. I want to know if theres anything else I should do while i'm there. Any suggestions? Quote
ssanddemon Posted February 3, 2005 Report Posted February 3, 2005 Case match the cylinders. I got a special cyl. base gasket from Twister Performance an used it as a template. Scribed along it on both the case and cylinders then ground away the excess metal. It makes for a smooth transition from the cylinder ports to case ports and supposed to be good for a few hp. Plus it's an easy saturday project if you already have the upper case off. Quote
Leadfoot350 Posted February 3, 2005 Report Posted February 3, 2005 Ya that is good for about 2hp so it is well worth it. You could put on new crank bearings if you want too. Quote
