tundish2800 Posted March 29, 2009 Report Posted March 29, 2009 You dont need to get the case trenched for a 4mm crank. Quote
lowbuckracing Posted March 29, 2009 Report Posted March 29, 2009 You will need a 4 mill crank,A cub cylinder ported for the 4 mill of your choice,pistons for the 4 mill,domes cut for what type of gas you are running,carbs,filters and intakes to feed the new build,Adjustable stator plate if you want it to run top knotch and the complete gasket set for a complete engine build.Just a few things to think about..You can also put a 4 mill crank in your stock cylinders and have it ported for the new crank,run stock carbs with bigger jets,have your stock head cut for the new pistons youll be buying and run the piss out of it..If your gonna talk to a pro about it call Kevin from HJR and he can point you in the right direction.760-815-1316..Kevin..dont tell him Lowbuck sent you or he will tax you for it..LOL Quote
