Title: Cylinder Wall Thickness Sonic Checked My 428 CJ Block
Post by: dozz302 on May 14, 2024, 10:42:19 PM

I just finished sonic testing a 428 CJ Block. The thinnest point I found was at the bottom of one cylinder at .138". That one spot about 3/4" from the very bottom on the Minor thrust side. Very small isolated spot then the numbers started going up. All other numbers were pretty stout. I'm assuming this block could safely go .060" over? Currently standard bore. If I remember all 8 Major thrust sides (thinnest measurements) were between .185" and .235". Did 8 points per cylinder. I was kind of surprised that the cylinders do seem to have a little bit of meat. At least on this one.

Probably but why 30 should be fine. I don’t think going to 60 is gonna outway the benifits of a thick cylinder. JMO

Should be just fine , but general discussion would be a better place vs the classified section.
