Olds casting number help

I am trying figure out what engine i have in theis '50 olds that i bought. the body is a 1950. the heads have a number 7 on the center exhaust port, which i think is a 1954. the problem number is the block. it has the number 563922 on the bellhousing on the p***enger side top. does anybody know what block this is? i measured the bore which is 4 inches. the stroke is approx. 3.5 inches. is this a 324 block that is punched out .030-.040? or is it a 371? hopefully somebody out there can give me a direction to go in. thanks

 

You might thry the American Automobile Casting Numbers Club.They're into stuff like this.Their web site is www.aacncclub.com

 

Look at the left side of the block, between the exhaust ports, there's a flat spot with the engine number stamped in.

Cubes Bore Stroke

324 3.875 3.4375
371 4.000 3.6875
394 4.125 3.6875

 

568922 is a 324 block

 

I checked. it's a 3 not an 8. Thanks for your reply.

 

i think i have a match with the #7 heads. The numbers on the driver side deck are V2####. i beleive i have a 54 324 punched out to a 4 inch bore. Thanks for all of your help, I really wanna run this engine and not "just drop a 350 in it", like all the sheep keep telling me to do.

 

by the way, is that Bukowski as your icon? Nice.

 

I'm not doubting you,
it's not what I find in my books or on line..?

yes it is Puke-kowski

here's a link to some #s

 

It sounds like a 324 bored .125 over with standard size 371 pistons in it, making it a 345. Since the 371 had a taller deck height to componsate for the longer stroke, the compression height stayed the same as the 324 piston.
