Branded Posted August 28, 2017 Report Share Posted August 28, 2017 I'm going to start searching for a 230 engine for future use. Other than having an 8 bolt flange on the rear of the crankshaft what are some othe ways of verification. This will be used in my 49 Wayfarer Convertible, I have noticed a external hair line crack in the water jacket near the starter. Doesn't leak enough to make a wet spot, just enough to make a stain.

plyroadking Posted August 28, 2017 Report Share Posted August 28, 2017 I usually just go off the numbers stamped on the block to determine what size it is. 1 Quote Link to comment Share on other sites More sharing options...

40plyguy Posted August 28, 2017 Report Share Posted August 28, 2017 I'd go by the stamped numbers. The crank having 8 holes doesn;t guarantee that it's a 230 either. 1 Quote Link to comment Share on other sites More sharing options...
Branded Posted August 28, 2017 Author Report Share Posted August 28, 2017 I just learned something, thought only the 230 had the 8 bolt flange for the flywheel Quote Link to comment Share on other sites More sharing options...
Reg Evans Posted August 28, 2017 Report Share Posted August 28, 2017 If the stamped engine number has been removed you can determine if the engine is a 218 or 230 by removing the small pipe plug over #6 cylinder and measuring the stroke with a piece of wire. 218 = 4.375" and 230 = 4.625" 1 Quote Link to comment Share on other sites More sharing options...

Yes I am, weighing my options on finding a block that isn't cracked and rebuilding a 230 or possibly going with a later model 318. I'm leaning towards staying with a 230, I like the flatheads.

Branded Posted August 29, 2017 Author Report Share Posted August 29, 2017 (edited) Located a 230 engine and Poweflight 2 speed automatic out of a 1954 Plymouth. Motor and trans is all together. Anyone able to tell me if this engines crankshafthas the 8 bolt flange to accept a fluid coupling from my 49 Dodge. I don't want to ask the fella to break the engine and transmission apart and waste his time if I can't use it. Owner of the says it's a 230 engine but from what I've found Plymouth didn't make a 230 until 1955.

I'd guess good chance one with a powerflite is also a 230 Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted August 29, 2017 Report Share Posted August 29, 2017 look for a diamond stamped on the 54 model engine number...if there, it is a 230, if not a 218...this is the only year Plymouth had two L6 engines of different sizes...it became the standard single L6 in 55 till end run and returned to standard engine identification number.... 1 Quote Link to comment Share on other sites More sharing options...

I only know what I read and sometimes cant trust the source or my memory ... Pretty sure that all 230 cranks will have the 8 bolt flange. Waiting to see if I guessed correctly! 1 Quote Link to comment Share on other sites More sharing options...
greg g Posted August 29, 2017 Report Share Posted August 29, 2017 I have a P28 engine (1956) 230 with a 6 bolt flange, just to throw that mongrel into the kennel. Are you certain the 54 set up is power flyte and not a hydrive? Cuz that's a horse of a different color also. Just more fun stuff you find out about these different setups. What was the last year for fluid drive?? Quote Link to comment Share on other sites More sharing options...

It does have a diamond stamped on it, so I suppose this would be a 230. Quote Link to comment Share on other sites More sharing options...

No I'm not certain it's a power flyte just going by what the seller has told me, he's going to pull the transmission and check the crankshaft flange and get back with me.

Plymouthy Adams Posted August 29, 2017 Report Share Posted August 29, 2017 I have read one book that gave reference to number of bolts holding the torque converter as having 8 bolts for 53/54 and that was in reference to the Hy-drive....and in the two year period it was available it had internal running changes..

greg g Posted August 29, 2017 Report Share Posted August 29, 2017 Aware that Plymouth didn't have fluid drive. He is looking for power plant for Dodge. So not sure the Plymouth flange will mate to Dodge components properly. Quote Link to comment Share on other sites More sharing options...
Veemoney Posted August 30, 2017 Report Share Posted August 30, 2017 These old cars don't always have the original motor in them. If you have not done it yet, I would suggest to have the seller send the stamped motor number to confirm what it is and then you will know what it came out off. You would still need to verify the stroke using the #6 plug method mentioned earlier as it may have started life as a 218 and someone replaced the crank to make it a 230. I have seen Plymouth motors in dodge trucks for example. Quote Link to comment Share on other sites More sharing options...

I have seen Plymouth motors in dodge trucks for example. My 49 Wayfarer has D30 stamped on the block, this denotes 230 from my research. I'm assuming it's the original block because my car was titled with the block number. When I bought the car 2 years ago and brought the car to Indiana I had the car titled using the body serial number just in case the engine was ever changed.
