Not Again!!!

You just need to keep your trap shut! That's just not possible with you. Bore is 4.055 and the stroke is 3.8976. We go from snuffer to Stuffer, or Stroker, or Slickster, or JOKER. Epic Fail Again. :nail::doh::eek:wned:

Wrong, AVG is what i posted, there accually all over the place from the factory. .008-.010 variance!!! But what would you know you measured one set of d-max internals in your life!
 
WOW!

Do you listen to what you say? Do you think before you post? Why would you put avg. as you call it and not a real number if your going to put anything? LMFAO AGAIN

Are you sure about that? You would need varying size pistons and rings...it would make no sense from a manufacturing standpoint.

Both LB7 blocks I have from totally random sources are 4.055 right on the money.

Isn't 4.060 rounded up from 4.055? Same with 3.900 and 3.8976?

Exactly, you talking less than 5 thou on the bore and less on the stroke, thats about half the thickness of a sheet of notebook paper....

Also the temp at which the blocks are measured can change deminsions a few thou BTW

It would take a difference of 100F or more to get the numbers you're quoting.

I still would like to see some examples of this wide bore variance using gauges that are worth a damn....because I don't believe it.
 
Wow thats a big factory tolerance like its 1909 or something. Ill look at what the bore tolerance is on a Mack tomorrow. My guess is less then +/- .001
