Blocks - check the cylinder wall thickness !
By Royce Peterson - 11/30/2003 12:10:30 AM; IP 64.12.96.238
Geoff,
It was a typical non - CJ 428 block from a Q code full size Ford / Mercury. The drill bit test proved it was not worth performing a sonic test on but the owner, a friend of mine insisted on a sonic test anyway. The block is useless junk, it was a miracle that the cylinder walls are not cracked after 150,000 miles of use. However it was being used in a low performance application so it may have just been a lucky fluke that it lasted this long.

You can also find "A" marked blocks in CJ Mustangs and Cougars built in the 1968 model year. They are normally thicker walled than a 390 but not always. And the 428 logo in the water jacket is no help to you if the cylinder walls are thin anyway is it?
