Hey guys, just picked up my olds rocket and trans and guy thought it was a 303....bit the number on back is 563922 and does not match the 54-56 324 number which is 568922.....so is this a 371 I have?
I don't know anything about the numbers. What do the exhaust ports look like. Do the center ports have 3 bolts or 4? Look on top of the bell for other numbers. For instance my 394 has the bore cast into the bell. Ah hell I can't be much help for ya other than priming the pump here. Post us a picture, common I'll show you mine of you show me yours. Glad you found a mill by the way. KUDOS.
No, a 371 would have a much higher #, not lower. You likely have a '52-53 model 303. My '50 block is 555611.
There should be a big number stamped on the heads ie. 8 or 10 etc. 8=55 and 10=56. If you find the number then it will give us idea of what year it is, however the heads are interchangeable for a few years but if they are original or at least the correct year they will help ID your motor.
mndodge, you really need to put up some pics of that junky old motor for the Olds guys. They will do one of these: Anyways, on my 55 and my 56 blocks; there is a large number 8 on the back bell extension on the 55 and the 56 has a big 10. On the sides of the block by the core plugs, there is a number 10 on the 56 on both sides. Have not looked at the 55. Now look for the number that was stamped into to the machined surface of the block where the head bolts to; look on the drivers side between the forward and middle exhaust port. There will be a small long spot of the machined surface showing there. That's where the stamped number should be. Hey, my motor did not show up yet today as planned; the guy is hauling a early 20s Chevy on a trailer and my motor in the back. He was on the Geo Washington bridge in NYC early this morning, someone stopped in front, and then he popped a brake line I can put up a pic when it arrives today......show me yours and I'll show you mine
Here is where the stamped number will be, unless the bock was decked a lot. That small area will show even with the head and exhaust still on. and I just checked my rear casting number on my 56 block; it does not match either of your numbers in post 1.
mndodge; i just looked at your pics; the carb is 56 or newer Rochester "Powerjet". 55 had the normal looking Rochestester 2G. I don't spot anything on the block that helps me date it, except I've never seen a #9 block before. I thought the real early 303 were not marked that way, and the later 303 had lower numbers. I want to think this motor is a 57 371 BUT you'd better put up those pics! You are running with the big dogs now Oh, the trans is not a GM T-10 .....I don't know what it is, can't see much. Kinda looks like a Ford front pattern, So if it has 3 levers, it must be a T-10 very,very early Ford muscle version. Does not look like a trans-dapt bell, maybe Cragar?? What's that funny distributor and "diecast covers".. he he EDIT: pull a valve cover to see if it's got adjustable rocker arms. Might have a hot cam with that ignition.
listen to F&J, like we have said several times the only way to identify the block is with the STAMPED numbers on the deck surface not the cast numbers at the bell that said, I do have a '55 324 block with the cast numbers 563922 at the bell the #14 is an early '57 head and the #16 is a late '57 and possibly early '58 head
Paul, you got to see this motor. I have never seen these valve covers before. The motor might be a mutt made up of different Olds parts, I can't see enough. it's all old parts. I am clueless why this has a single Powerjet. Maybe it had 2x4 4x2 or 6x2 that was too much for the street.
Ok guys, heads are off and got pictures......give me a few minutes and I will try and load some pictures. F&J.....check your email, YOU GOT MAIL AND PICTURES!
Ok did a little s****ping and here is the stamp # V 640 895 Also, on the extended bell, there are 3 circles that are cast in and they have screens in them......??
A few with the screens in extended bell and also valve covers that were in it.......has a schiefer clutch disk in it, but bell and valve covers have no name or numbers.
stock pre 371 flywheel early '60s big Ford car transmission? never seen those valve covers either W&H Du-Coil distributor Hurst mounts don't recognize the adjustable rockers.. pop up pistons this was a race motor when it's racing days were over someone swapped the induction no way that carb was part of the rest of that package neat stuff
Paul.....What about the screens on the extended bell, seen those before? and now I am puzzled with the "9" on bell, F&J says he's seen 8 and 10 but not a 9......Is this an oddball?
you did fine, there are a lot of good parts there I would be pleased to find all that stuff in one package
Well it's like was said.....if this block is 324 and 4" and its toast, with the 9 on it....is this worth possibly sleeving or? The 9 has me wondering and are the screens something someone added or ?
It's a mid-1955 324 going by Jerry's info (DON_WOW) I was thinking this was a race motor inside, mainly from the ignition. Awesome score. Now you can run a 4 speed in your Model A, and still be period correct Someone had money to be able to do a 4 speed back in the early 60s...that must be around when it was run. My little 303 find that just arrived seems....boring. Oh well, the plugs looked good, no rust showing in bores, and a 3' bar thru the spokes on the front pulley...and it turns free. 1953 303 with factory Selector 3 speed stick. Nothing missing except air cleaner. Came out of southern NJ metal recycle place that normally does not do cars. I found a thread on aaca Olds section that was 3 months old. Some guy spotted the car there and put up a few pics. I totally screwed up by not enlarging the dash pic. Former hamber Coldwar did, and posted on there "It's a stick". I can't believe it sat there this long. It still has the clutch linkage part and the rear trans yoke
