David A. Posted April 26, 2009 Report Share Posted April 26, 2009 Hi, I have a engine I saved out of a 53 Dodge truck. From the information I have read on this forum I think it's a Plymouth engine, But I was wondering if someone could tell by the Number if it is a 218, or a 230 engine. The Engine number is P23*708499 and the casting date is 2-20-52. I'm Hoping it's a 230 as I am about to rebuild the engine in my 50 B2B and would like to convert the 218 in it into a 230. Any help will be greatly appreciated! David A. Quote Link to comment Share on other sites More sharing options...
greg g Posted April 26, 2009 Report Share Posted April 26, 2009 Plymouth switched to 230 in 54. I believe the P 23 predades that, so unless some one messed with it before is proably a 218. Atop the head over #6 cylinder is a square pipe plug screwed into the head. You can remove that insert a piece of stiff wire and measure the stroke. Make sure the wire is about 7 inches long. It will ride the piston and allow you to measure the stroke as you trun the engine by had through 1 revolution. Pulling all the plugs makes it easier to turn it by hand. 4 3/8 = 218. 4 5/8= 230. Swapping the crank and rods from a 230 will make the 218 a 230. Quote Link to comment Share on other sites More sharing options...
grey beard Posted April 26, 2009 Report Share Posted April 26, 2009 Can you find the flat coupon-shaped area just above your generator, near the front of the engine and just beleath the cylinder head on the block? It will have a few numbers and letters stamped in it. These code numbers will tell the size and provenance of your engine. Get that info and we can help you out in a jif. Good Luck Quote Link to comment Share on other sites More sharing options...
pigheaded Posted April 26, 2009 Report Share Posted April 26, 2009 Hello, This is a link to a site that tells you all about the flat 6. From your number a P23 is a 218ci built for a Plymouth Car in 1952. http://www.t137.com/registry/help/otherengines/pengines.html Thanks, Jerry Quote Link to comment Share on other sites More sharing options...

Bradley S. Posted April 26, 2009 Report Share Posted April 26, 2009 Wow, that was fast. Thanks! The truck I have is a dually stake truck. The model number is hard to read. All I can make out is B-1-??-126. Serial number looks like 80322752. Do you know what model this truck is or is more information needed?

Bradley S. Posted April 26, 2009 Report Share Posted April 26, 2009 Oh, and it has a 4850 GVW. Quote Link to comment Share on other sites More sharing options...
townwagon Posted April 26, 2009 Report Share Posted April 26, 2009 80306001 to 80355593 is the 1948 B-1-F, FA, HH, HHA, FL and a few more, but the only one that is rated as a 1 ton is the FL. All the rest are 1 1/2 ton and 2 ton, which would have a larger capacity. What size are the wheels? Does it have the bolt on fender lips or are the fender lips part of the main fender?

Young Ed Posted April 27, 2009 Report Share Posted April 27, 2009 Hello,This is a link to a site that tells you all about the flat 6. From your number a P23 is a 218ci built for a Plymouth Car in 1952. http://www.t137.com/registry/help/otherengines/pengines.html Thanks, Jerry I just looked and there is a mistake on that chart. There are no P22 engines. P23 engines were used in both 51 and 52 plymouths. The model number was held over due to the Korean war Quote Link to comment Share on other sites More sharing options...
David A. Posted April 27, 2009 Author Report Share Posted April 27, 2009 Just wanted to say a quick thank you to everyone for your help in identifying my spare engine. I'm dissapointed it's not a 230, but at least I know what it is now! Anyone know a source for a 230 crank and connecting rods??? Thanks Again, David A.

townwagon Posted April 27, 2009 Report Share Posted April 27, 2009 Are you sure the GVW is 4800 and not 14800? Try and clean up your tag a little bit better so you can read the model number and GVW, sometimes using chalk or something on the numbers will make them easier to read.

Bradley S. Posted April 27, 2009 Report Share Posted April 27, 2009 Eric; I think you are correct. It's a 1-1/2 ton. I must have written down the GVW incorrectly. I will take a second look. Thanks for the help! Quote Link to comment Share on other sites More sharing options...
