Ec250-300 big bore kits ?

Does anyone do a big bore kit for the ec engines? I see a guy selling a ec 300 stating it has a 350cc kit fitted anyone heard of this or got any info ?

Never heard of that. I don't know if there would be enough material to go out to a 350. I'm sure some will chime in with more info.

I had Eric Gorr build my 300 into a 327 using a 76mm piston from a big bore Honda ATC piston. You can do a search on this forum for the details. I do not believe there is enough cylinder material to allow you to go much bigger than 76mm on the bore. If the 350 is for real, he probably had to stroke the crank as well.
