Checking for decked block on 327

Re: Checking for decked block on 327

You're confusing stroke with crank throw radius. Crank throw radius is half the stroke, so if stroke is 3.252", then the throw radius is only .001" high.

On a typical engine if you see +/- a thou or two random variation along a deck with no indication of tilt, you've got a straight block and good rotating/reciprocating assembly. It doesn't do much good to get it tighter than that - even on a racing engine where you are usually looking for maximum CR.

Duke, that's what I like about you.
You have an eye for detail, and I'm glad to see that you reciprocate for the times that I correct your posts.
Attached is some chicken scratch from a late September 2009 project log entry:



I have duly corrected the above post, for the benefit of those with a less discerning eye.
