This is called a Hemi Wedge. its a hemi short block with max wedge heads. they ran them in NASCAR after the hemi ban. I know someone left a message saying its a 426 wedge. that person was wrong. I know what it is cause I got a few of them. this is from the Petty collection of motors and parts I own. I also have the original motor from the 64 Daytona 500. and a bunch of factory proto type parts.

Actually the 426 wedge was not a hemi wedge. The cylinder heads will not interchange on a hemi block because there is no accommodation for the oil to drain back to the oil pan on the wedge heads. Most of the rest of the internal components are interchangeable and even though the push rods, lifters and cam will fit in either block, the pistons, push rods and cam for the wedge cannot be used with the hemi heads.

they use a hemi short block and max wedge heads. it works! I got one. and know of quite a few others its allot of machine work but they do work. Petty's won allot with them as did allot of other people.

ever heard of a 383 Hemi? 383 short block with hemi heads?the hemi wedge uses a special rod and piston. I have worked on on these weird combo's. I actually own some of these cars. I know what I am talking about. if you research in the direct connection books from back them you can buy the parts to do this, I still have the books and blue prints on what to machine and weld shut.and with the 383 hemi, Ronnie Sox set a few records with the one in his Omni as did Billy the Kid and a few others. the first one to do the 383 combo was Dave Rupp in his 65 Dodge.
@ron-phelps13 years ago I would really like to see one of these hemi/wedge engines disassembled to see how they were modified to work. I'm looking at the SP3 Circuit Car Performance Parts catalog as I'm writing this and it does not show the blocks but the rest has separate part numbers for wedge and hemi applications. I run the Stage V hemi conversion heads on my 426 wedge block and it needs external return lines for oil that gets up into the heads. Thanks Ron Phelps
@ron-kirkpatrick13 years ago
I have all the part numbers and paperwork from Chrysler on how they are done. the rods and pistons have there own part numbers. two holes on top of block welded shut 2 holes drilled and threaded each side on the deck. Petty's did most of them. they have a special intake for the max wedge heads. they are a domed piston. mushroom cam etc. really a good running motor.
@ron-phelps13 years ago
Ron, I would sure like to see that set up and those part numbers. They must have come up with a fix for the difference in oil returns between the hemi and wedge engines. Post some photos if possible high lighting the modifications you listed. Very interested and Thanks! Ron
