Sonic testing LS blocks results
Been playing with a new sonic tester we have here
checked a couple matters of interest
6.0 block bored 4.030" shows .220" on the thrust, it gets down to .180" at 3 o'clock position.
6.0 iron block bored 4.080" shows .200" on thrust, minimum .140"
LSX block bored 4.155" minimum I saw was .250"
241 cylinder head deck thickness, .360"
Dart 225 head deck .484"
I checked an LS3 block, dunno if I'm getting a good reading on aluminum block, I think its picking up the sleeve and the aluminum behind it. At 4.070" in various spots would show .120"
Checked an LS2 block bored 4.030" showed a minimum of .120"

This block thrust; is it a matter of deflection you are speaking of on the trust bearing cap? I guess a few of us who are unfamiliar need to know what those numbers correlate to
