i was planing to buy a kit with the sleeve, but which is better 313 or 330 for reliability and still have good power agian will a 330 smoke

I will get the 330

[Sjorge450R]

they both use new sleeves, so as for reliability, the are both the same. They will both smoke if you dont take care of them (like not shooting the hose down your exhaust ppipe) If you get either of them, I reccomend getting a cam and oil cooler. and mabey even a small port job.

[kyleschonert]

get an FST300 kit, Curtis Sparks x-4, and a port and polish job. we havent even put a cam in in mine and this thing hauls.
