FE Technical Forum / Cylinder Wall Thickness Sonic Checked My 428 CJ Block
« Last post by dozz302 on May 15, 2024, 01:32:31 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.
I have no plan on going .060" over.

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

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

Congrats on a great day of success! The car is looking awesome. Then again, you could put that engine in an Escort and it'd be the coolest car around. ;D

Nice attention to detail on the build. I hope you'll post some more after the paint and final assembly.
