RE: RE Pistons?

[Earl Helm <ehelm@xxxxxxxxxxxxxx>]

.055 over for a 440 is now a common size since that is also 
a chevy size piston. I have used .055 in a 15 to 1 - 500 inch 
440 motor with no issues.

They said 0.060 was OK all day long on all B / RB blocks.  If I figure
correctly about 0.062 + /- is the difference in the 413 & 440 bore.
Should
be no problem??  I have bored B / RB blocks out 0.063 and more for
clearance
with NO problems.  Maybe I was just real lucky but the article seems to
back
me up.  Just my II.

Good read, thanks. I don't see anything there that contradicts the
argument
not to exceed a 0.040" bore on a 413 to get to 440, though.
