Here is a great 413 Industrial Block out of the Oil fields of So Cal.
Never overheated and low hours run only on Propane.
Still standard and nice
Hot Tanked/Magged/Pressure Tested
I bought six industrial Blocks in the late 1970's AND
this particular block Sonic tested the very best of them. However, my Max
Wedge racing days are over. I saved this one only as it was
the best!!
I would not hesitate to bore it 426 or even 440 if it was me.
Late 72 casting
$395.
