I think this was someone's heavy handed approach to saying, "NOT FOR RESALE" ...no $h!t !! 7320249-IMG_6635.JPG (136 downloads) Last edited by autoxcuda; 08/03/12 05:03 PM.

The HEMI fuel block was 3690010 No (normal)casting numbers Some Marine blocks had the webbing on the skirts and some not. Some had webbing and 2 or 4 bolt mains. Curious http://www.justanswer.com/boat/3xm5m-recently-purchased-426-chrysler-engine-told.html the old moparts discussion I mentioned: https://board.moparts.org/ubbthreads/showflat.php?Cat=0&Number=6151728&Main=6151567 It correlates for me

That was before digital cameras or cell phones so I wasn't able to get a picture. But it was the same deal. Wedge block with cross bolted mains and a 1964 date stamp. He said he had gotten it from a NASCAR guy.

IIRC in mid 71 Chry made a small run (100 or so)of 426 wedge blocks for Nascar and drag racing.I can't recall if the bosses for the cross bolts were cast in.I do believe there was also some IND and Marine 426's that included the bosses for the cross bolted mains.I rebuilt a pair of Marine 426 many years back that had the cross bolted mains but the rest of the parts were 426 S type parts plus the marine gear and the gear drive for the reverse rotation required for one of the dual marine engines. Leave the gun.......take the Cannoli's....Mike

The thing that made it better than a typical '60s cast 426 block was it used a 440 water jacket making the cylinder walls an extra .070 thicker. Dvorak did have a cross bolt wedge block at one time but I believe it was a converted Hemi block. Back in the days before aftermarket BB wedge heads, I saw a set of heads that had no casting numbers, the external appearance of a 452 head and Max Wedge size ports. The owner was from NC and said they were used by Petty after the Hemi was banned and before the small block program started.
