The quick answer is yes. But there may be some stuff you need to do to make it work. I was looking at a 440 kit that stroked the crank and used a 426 jug and piston. So- it's doable, just don't know what all is involved.

Is that 440 better than the 444 kit from lukes racing? anyone have an opinion?

I though the diameters of the piston pins were a different size.Maybe Im wrong.I never did it, but I thought I remember hearing some thing about it

The pin diameters ARE different. If you are going to run a 426 piston and cylinder, you have to have your crank rebuilt with a 426 rod as well.

yes, i see from that site also that the 400 has a smaller crank. INSTEAD of getting your cranked stroked, has anyone installed a 450 crank?
