    if it is an 1956 322, you got the best 322 nailhead atleast.. i mean the 1953 wasnt so good, much more heavier then the 1956 one, and ahwell..

    Post the numbers stamped in the block deck opposite the dip stick and I can tell what it is, 57 and later motor will be stamped just in front of valley pan.

    Easy way to tell the difference between a 322 and a 263 is a 322 has a harmonic balancer. The 264 does not.

    I've got a 264 in the 32 right now. It runs good but wasn't easy getting parts or info on it. I had to figure a few things out for myself. The tranny (manual) was my buggest pain in the ass.

    Judd ...this is one of the reasons I hate nailheads. I get conflicting information all the time. Even from the experts (nailhead message board).

    When I was trying to find out what my motor was the expert told me you can't tell by the casting #s. The best way to tell is by the balancer.

    I guess I'm back to not knowing what's in my 32.

    well i don't think the harmonic balancer bit is going to help me. both of mine don't have one but one is just a short block and the other is missing parts off of it, and both have a threaded and keyed crank. any other clues? does anyone have any stock valve covers i only have one for both motors, need 3 more.

    if its the nailhead out of 1096's truck,,then i do know its a 1955,,,cuz i took it out of my buddies 55 buick special. he was supoosed to install a BBC in his car(car is still sitting),, it was a 2bbl engine.. it was in great running shape when we pulled it...i think i read you rebuilt it though,,

    but to make things even more confusing,,i believe that motor or heads may have been replaced or rebuilt at some time since it had the lil "hot " tags on the heads(the tags that engine rebuilders put on rebuilt motors to know if you got them hot or not if there is a waranty issue..

    sorry ,no help,,but i was kinda thinking it was a 264 since it had the 2bbl on it..

    Sam ...that is the motor out of your old truck. I didn't rebuild it and it runs great. I've got a 56 322 with the harmonic balancer that will get rebuilt and go in the car in the future. It was also a 2 barrel motor. The mystery continues :D

    Do you know why there was a set of holes drilled in the valve covers?

    by the way one of my motors has a 4 barrel intake on it but the other one is missing the intake. does that help on identifiying the motor.

    If its the original motor and the aircleaner is also. Then yes it is a 425.

    My take on the 264 is not to use them if you can find a 322 or bigger.

    Marty gave me the casting numbers for 425 blocks but I'll be damned if I can find them. I called a guy about a suposed 425 he has for sale that came out of a 67 Riv. He said he couldn't find any engine numbers in front of the valley pan, but there are numbers cast in the block on top of where the trans bellhousing bolts up. He said they are B1364705. This is the same number that's on a few of my 401's. Can this casting number be used to identify 425 from 401?
    I need to get back to this guy, so any help is appreciated.
    Thanks, Keith

    I found the casting number on a Buick site and it is calling out a 64-66 401/425. How can I determine if it's a 425. The owner said it has a single 4-brl.
    Help?? Thanks, Keith

    All Buick engine blocks has a two bolt main bearing cap bottom end. The easiest way to tell them apart besides checking the various bore sizes is to check deck height. You can also check the engine identification code. 1966 had MR for the 401 325hp "400" Gran Sport. MT for the 401 325 hp. MW for the 425 340 hp. MZ for the 425 360hp.

    This is why we need the ID number. If you have a stock valley pan it will point right at it. There is an arrow stamped on the pan toward the pass. side of the pan and it points to it. You will find it just ahead of the edge of the valley pan on the same surface as the gasket.
