[TORO1968]

I'm looking for a decent 400ex engine to build up...preferrably something that hasn't been modified too heavily. Let me know what you guys have for sale!

Thanks,
Jordan

how in the word did you get your motor to 420???
you can get a 416 with is .080 over and a 426 with is .120 over.
Did you get a custom made piston that is .100 over???
Or did you just mean that it was bored to .020 over.

Not bashing just want to know.
