426 ID help

[lugnutx2]

New to Mopar, so I know very little about them and need some help. I just traded for a 67 GTX and the seller was positive it has a 1964 426 max wedge short block with 440 top end. I just got the car today and haven't had time to check all the block #'s yet, but did find these: The pad by the distributor is stamped V 426 1 24 HP and the front face of the block has casting AAQA 1R. I haven't found the blocks's casting # yet? Any ideas as to what this is? Thanks in advance!!

sounds like a max block or could be...all maxies were high nickel block with AAQA cast on front of block in large letters.

 

[lugnutx2]

Yes, the AAQA are large and are cast in the block. I guess I'm going to drive the car some and see how it is on the street, a previous owner had installed the engine for racing and I don't have any specs on it.

be careful...even streeet max is 11.5 to one compression with bigger combustion chambers in max head , compression could also be
as much as 13.56 to one ....wow ! so use the best gas you can buy and watch timing to prevent detonation . just a little detonation will melt ring lands in pistons , so again be careful !

V 42 Designates It As A 426 Street Wedge Block! But In A '67????

He already knows it is a 64 motor and not original to the car. If the motor has a 440 top end, the heads could be 915's, 906's or later 452's so the compression may be lower than a stock 64 street wedge but not much if the pistons have never been changed.

Post a picture of the engine pad.

Post a picture of the engine pad.

THE PREVIOUS OWNER THOUGHT THE HEADS WERE 906 CASTINGS, i'LL CHECK TO BE SURE AND TAKE A PICTURE OF THE PAD TODAY. I've never posted a picture on this site before, hopefully I can figure it out.

Here is a picture of the pad. Notice the numeral "6" stamping is different.

Did you read the other thread about how to identify a true Max Wedge block?

You may need to prepare yourself for some information that conflicts with what the buyer told you.

Yes, I read all of that and have decided it's a street wedge, someone requested a picture of the pad, that's why I posted it. The car was cheap, seems to run good, and if it had been a max wedge block, that would've been icing on the cake. Thanks to all who helped.

looks like a homemade 6 to me.You better check the casting numbers.

2406730, yeah the numeral six isn't factory

this is what a hi compression mw pad looks like

here's what a hp pad looks like as you might notice the 6 is also missing here or is very lightly marked which seems to be common on these dates must of been a bad beer day at the plant??

Thanks for the update!

That 6 was added by someone who probably thought it was missing from the factory. It looks like they used a punch. LOL But I believe the street wedges only had the 42 on them - no 6. Here's a pic of mine.

His Opening Post Sounds Like He Wasn't Sure If It Was A 426 Street Wedge!!!!

A Max Wedge will have "MP" after the year on the stamp pad. A 64 Max will be VMP 426 where the V designates 64 and MP designates Maximum Performance. Max Wedge is short for "maximum performance wedge head engine". What you have is a street wedge HP and a nice find for someone with a 64 Fury. Or just run it if it's in good shape. I'm putting my old 426 block into action in my 69 RR.
