Thanks for the info. I have been told that a 6.4 was a much stronger block than the 6.1 or 5.7. I have also read conflicting reports on which block is the thickest, and has the best main webs.
Can you shed some light on the subject?
Thanks!
It's been awhile since I looked at a 5.7, 6.1 vs. 6.4. I will look at them again tonite and compare the differences.
