Wiseco 440 kit?

[ZJTurbo]

Looking for more power. I saw the Wiseco 440 kit in my Moutain offroad mag. for only $260.00 sleeve/ piston/ wrist pin/ rings/ gaskets etc... I thought they were much more expensive than this? I am an avid wrench head working and building my car very often. I was told it is a pretty simple swap just getting the sleeve can be a ******. I was also wondering what a good shop should charge me for such work? This will be going along with my full exhaust/ jet/ intake/ hotcams/ suspension.

To put in the new sleeve and bore it to size will be between $100- $150. I would say do a 416. Built right it will be as fast as most 440s plus you dont have to have a new sleeve put in and you can still bore it to a 426 when it wears out. Basically you pay less money and can still be just as fast. Compression makes more of a power difference than the bore size. Im not saying bore has nothing to do with it, Im just saying compression does more.

Im just saying compression does more.

is the 416 kit just a longer arm or is it a domed piston?
