Seems like I remember seeing a pic of a Petty car that was a wedge, but had the cross-bolted mains... Might be a good one to have

was thinking something similar. looks like something out the back door of petty enterprises

Looks like a standard wedge block with cross bolt mains added by machine shop....No casting numbers Hmmmmm........

Looks like a standard wedge block with cross bolt mains added by machine shop....

Except the block has the extensions going to the main caps cast into the block skirts. This block was cast with cross bolting in mind.
Looks like what Ford did with their 427 Side-oilers back in the day. Pretty cool stuff.

If Chevy can make a "Mystery Engine", so can't Mopar.

Hey, that's local to me. I wish I knew anything about engines - it might be fun to run over and check it out.

If somebody finds out more about it be sure not to leave us in the dark.  Odd piece there.

Could you add those extra bolts on any block ?
