I was hopeing i could wait till the winter to do my top end but dont think its going to last that long. At the moment i have a stage 2 hotcam with the spring kit. and idk what kind of piston or bore. But what i want to do is a 686 big bore with (supposed to be a 686 now but havent had it apart to see) a 11:5 high comp weico piston kibblewhite vavles and dual rate vavle springs. Now does anyone have any suggestion they would like to add? has anyone used kibblewhite stuff? is it good? and does anyoe use the dual rate springs? are they good? any feedback, advice, or suggestions would be appreciated. Thank you.
