Were all 426 WEDGE motors stamped HP??

Were all 426 early WEDGE engines stamped HP?? Not not.....how did this work? Stumbled across a 426 wedge HP engine with a 67 440 intake and carb on it. Thanks in advance!

64 max wedges were stamped MP, and all the 426 street wedges that I have seen are stamped HP. It is a pretty small sample size though.

The 426 SW in my '65 Monaco is stamped with HP. At Carlisle approximately 10 or so years ago was a '65 Coronet(if memory serves me) and it had a 426 SW. I asked the owner if I could look at the engine plate and it was NOT stamped with the HP.

Thanks all. I might have read that if it’s stamped V 42 that it’s a Max W motor and if it has the groove cuts atop the cylinders. Crazy how they did things back then.

The V stands for 1964. The 42 is 426 displacement.

All 426 Street Wedge blocks were stamped HP.

All 426 Street Wedge blocks were stamped HP.

No they were not. See my post(#4) above. Don't know the numbers on how many were or were not but I witnessed at least one that did NOT have HP stamped on it.

How do you know it was the original engine?

For reference only:

This block came out of a 65 Monoco. The guy that I bought it from pulled it out himself so I know it’s origin.





This block is a 64 B-body. I say B-body since the largest engine in a C-body at that time was the 413.

Here's a street wedge I used to have. These are all the same block with different lighting to show the stampings.
