I could use some recomendations for some parts to get alittle more from my beater. I need a top end, I dont need to jump to a 440 just yet so a 416/426 will do if the stock cylinder is in good shape. So good piston / compression ratio? What brand piston? (on pump 93) I read that some Wiseco numbers are not true compression ratios? I also want a cam. I do a good mix of high speed/slow trail so I need a good all around cam. Looking at the Hotcams stg 1&2 I will do some light porting my self and thats about it. I dont really need a crazy valve job or expensive carb. Anyother internal parts I should get? Do I need to do anything to the head? I currently use Amsoil 0w-40. Jetting suggestions are good also. I run 20inch tires so gears are a option also. Thinking about adding a tooth in front. Thanks...
Current mods are in my sig...

i would go with a 416 JE Piston 87mm bore 10.8:1 you will still be able to run pump gas. and get a stg1 or 2 hot will be a grate set up will add lots of torq.

Thanks. Where is the best place to get a JE piston? All I have here is a Rocky Mtn book and all they list is Wiesco. Anybody else with cam suggestions?
