what is involved in puting a 426 verse a 440 ? 2001 HONDA 400EX FMF FULL EXAUST K-N FILTER DYNOJET KIT NO AIRBOX. JDPERFORMANCE ARMS WORKS TRIPLERATE SHOCKS. LOOKING FOR ALITTLE MORE TOP END.

 

I hear you don't have to resleeve the 426. That would make it easier and cheaper. A lot of people on here seem to be very happy with theirs. I have the 440 and can tell you that if you don't mind spending more it is a very nice thing to have

 

426 uses the stock sleve, and a 440 requires a big bore sleve. So the differnce is about $150-$200.

 

who do you recomend doing a 426 kit . where do i get the piston.

 

Go with a 416 my little brother has a 416 with a port job, stage 3 racing cam,39mm carb and a curtis sparks pipe. He eats raptors for lunch all day.

 

I say the 416 because when the bore is wore out you can then take it to 426. Check powroll.com for a piston or big bore kit. They did my stroker and it hauls butt!

 

i would also say the 416 since the sleeve is too thin and has a possibility of breaking with the 426. i am actually running a 406 and the power increase was dramatic. i am using a stage 2 hotcam with it. you will get more top end out of this. by doing this, you not have enough power to play with the gearing for more top speed if thats what you prefer. i am running 16/36 compared to the stock 15/38 so i get more top speed. it runs really strong.
