440 kit

[Dannys400ex]

how long does a 440 kit last before you have to rebuild it? i race local harescrambles and want the extra low end tourque, or should i just start out with a lower kit (416 426)

I don't know about the durability but if you want more low end....then stroking it would be a better bet for you. Boring is mid-top and stroking is bottom from the way i understand it

the setup i had really ripped on low-end, i would say more so than even a raptor. i had a JE12.5:1 piston, 440 bore...stg 2 hotcam, hmf silencer, and open airbox. the 440 kit with a je piston is awesome, the je is 10x better than wiseco IMO
