Re: 350 or 400?

stay away from the 400................they have a design problem with the siamesed cylinders and will not last as long as the 350. The cylinder bores go out of round due to uneven cooling and they turn into oil burners.
You can not just bolt any 400 flywheel on there either. The whole ASSEMBLY will need balanced.
stay with your 350
