440 kit

[mack400ex]

someone tell me the most reliable and truest 440 kit between 300 and 450 bucks? (not a 416 or 426)and where can i buy it? also if their is a 416, 426 or anything else better than the 440 tell me...(i ride mostly fast trail riding and sand pits)

well if your only gonna spend that much its not gonna be a top notch job and i doubt it will be that good your quad is gonna be running alot hotter also.. i have mine in the shop right now for the 416 upgrade and its gonna cost a pretty good bit but you might wanna try searching this subject

you arent gonna get much for that price...and i personally like the 416 better for the woods riding and trials

I personally reccommend the 416 over the 440.Relabilty is the main issue,not to say the 440 is not reliable but I would feel safer knowing that I have room for another bore if something were to happen.I reccommend JE or Ross pistons and your choice of cam (mine TC's XC cam).Get some porting done to the head and you will be very satisfied.The differences betweena well built 416 and 440 are minimal performance wise.
