Do I need to change my clutch when upgrading the engine to 440?
What is best one, a hinson?

 

I am running my STOCK CLUTCH with stiffer springs on my fully built 440 (45hp) and i have NEVER HAD ANY PROBLEMS WITH THE CLUTCH WHATSOEVER. People will tell you that you have to upgrade your clutch ans so on but stiffer springs are all you need, 20 bucks.

 

oh yeah, it wont take much for your 440 to beat a craptor. Mine is about as built as you can get and craptors are no problem.

 

i did the springs also and the clutch is fine.
