Rich,
I would agree about the cylinder wall stuff, though I am guessing that the 400
is
a longer stroke.
In any case, whether or not you plan to blow away any records (laughing at my
own
chances here ;-) If you can go with the 370 that fits so nicely just under the
'C' class limit (guys, is there an over-bore eg. .030... allowance or would he
risk bumping up with 'wear and freshening' over time?) I would stick with that.
Think of all the motors that lurk in the 'B' class; 373-439. Then again, a lot
of the C records are higher than the B ones. How come guys?
Cheers,
Rick
