What is the best brand for a 440 big bore kit?

JE I hear pumps better than Weisco or something. I ordered a JE Piston, it's driving me crazy on the wait for it.

I have the JE 426,,, love love love it. Had a 440 it cracked and then I replaced the sleeve and went down to a 426.

I was too nervous hearing about problem with the 440's but have learned now that if you build it right and break it in right you shouldn't have any problems
I think one of the most important things it having your cylinder done properly and then installing the rings etc.. correctly.

Good luck.
