440 big bore?

[BrandonBlackmon]

What all is included in the 440 big bore kit for a 400ex?

Depends on the kit. If you send it to say, Duncan and say I want your 440 national kit then it comes with everything. If you want to do the piece your own kit together method you can buy the sleave, piston, and gaskets for around $325. Figure another $100 to have the sleave installed and bored to the piston.

$325:confused: I got a wiseco 440 piston, sleeve , gaskets, and a hotcam stage 2 for 290. but without the cam its like 180 on ebay. I got the cylinder bored at lindeys machine for 130.

I didn't want to run the wiseco. I bought an 11.2:1 ross. It is a little more expensive.
