51BuickWoody Posted March 28, 2020 Share Posted March 28, 2020 (edited) I've got a 51 Woody. I have conflicting evidence on what engine I have. The oil pump shaft and engine cast number suggest I have the series 50. However, the crankshaft bearings have a hole for oil distribution. The manual says that the series 70 has a hole in the bearing and the series 50 has a slot for oil. The manual suggest that the bearings on the series 40 & 50 are the same size but the series 70 is larger. Can anybody offer any help? The engine casting # is 63034055 Edit: Thanks for all the help. For years my father believed that it was the Model 70. But I believe we have the Model 50. The engine number behind the distributor is 1343404. The fender has 3 ports. I'll add more photos later.

Ben Bruce aka First Born Posted April 3, 2020 Share Posted April 3, 2020 I see you have not received an answer. I will try with the limited information. In your first post you say you have a Roadmaster. If so, unless some did something unusual, you have a 320 CI engine that came in all series 70 , or Roadmasters. The Super had a 263 CI engine. You posted a "casting" number. Needed is the Engine seriel number STAMPED on a machined surface just behind the distributor. A quick tell is the crankcase ventilation intake on the driver side of the engine. The 320 , Roadmaster engine, has this intake, about 1 1/2" x 2 1/5" located at the front near the generator mount. Super, 263, it is near the back of the engine. Pictures? Ben 1 Link to comment Share on other sites More sharing options...

Glassesguy Posted April 3, 2020 Share Posted April 3, 2020 What numbers are listed on the body tag on the cowl? Model 59=Super. Model 79=Roadmaster. Should solve what engine you have. Link to comment Share on other sites More sharing options...

51BuickWoody Posted April 6, 2020 Author Share Posted April 6, 2020 (edited) Super 50. Would have been nice to have the 70. I live in San Diego at the top of a 4 mile long hill. I was worried about it going up and down the hill. When my dad was driving it in the 70's he said it had plenty of power. 63030455 Edited April 10, 2020 by 51BuickWoody eng# (see edit history) Link to comment Share on other sites More sharing options...
Buicknutty Posted April 6, 2020 Share Posted April 6, 2020 The axle gearing and torque of the straight eights would provide pretty good pulling power. Keith Link to comment Share on other sites More sharing options...

51BuickWoody Posted April 8, 2020 Author Share Posted April 8, 2020 Our tranny was rebuilt a few years ago. The engine has good compression. I AM still trying to figure out why the crankshaft bearings have a hole for oil distribution when the book and all other evidence says it should have a slit in the middle. I'll add photos another day. Covid-19 has me keeping my distance from my father. The car is at his house. Link to comment Share on other sites More sharing options...

Ben Bruce aka First Born Posted April 10, 2020 Share Posted April 10, 2020 Most assuredly a 1951 263 engine from a Super, 50 series. The '51 50 series Dynaflow engine numbers began with 6,240,564 5. 1952 began with 6, 646,230 5. The final numeral separated from the seven digit number by a space is the series designation. I am unsure why your manual indicates what it does. My 1950 Shop Manual does not. That bearing looks just like all I have seen. Ben 1 Link to comment Share on other sites More sharing options...

Mark Simmons Posted April 11, 2020 Share Posted April 11, 2020 I remember reading some years back the difference between the 320 and 263 motors was the cc venting on the left side of the block the 320 was towards the front and the 263 towards the rear.....????

Yes. 263 and 248 at the rear. On the drivers side . Even without the engine number to check, the placement of the number tells us this is a small [ 248/263 ] engine since it is in front of the distributor. 320 is behind.

We don't plan on "showing" the car and really it's just gonna be a Sunday driver for my dad and I. We're on a pretty tight budget. Been where you’re at a few times! I believe you’ve answered your own question, tho..... ”Driver” being the operative word. Consider forgoing Or delaying cosmetic, bling, or comfort related items at this point. And spend tight dollars on driver related necessities. Your crank is exposed and you are so very close to a well executed ring and bearing job if the bores are in reasonably good shape. Maybe clean up the head and check for any questionable valves and seats. Worst case.....maybe a valve job. In the old car world.......not a lot of tight budget dollars to breathe “driver” life back into the car. Link to comment Share on other sites More sharing options...
JohnD1956 Posted April 12, 2020 Share Posted April 12, 2020 Why was the engine out to begin with? A problem? Or a desire to restore? As long as it is already out it makes sense to take care of the bottom end. It may save you from having to pull it again. BUT, can you just change the bearings without addressing the finish on the lobes of the crankshaft? Ben is right about using plastigauge to check the clearances. But if the engine was pulled because of a problem ( maybe a rod knock?) then there is no point in putting it back in without addressing that issue. 1 1 Link to comment Share on other sites More sharing options...
51BuickWoody Posted April 19, 2020 Author Share Posted April 19, 2020 Pulled the top bearings out. Timing pulley won't come off. I have a pulley puller. Haven't tried it yet but only because I didn't have time. Link to comment Share on other sites More sharing options...
