Andydodge Posted September 25, 2008 Report Share Posted September 25, 2008 Do Plymouth 201/218/230 engines all use the same size intake/exhaust valves?, ie from 1941 -59, also apart from under/oversize dimensions are the main/big end and cam bearings all the same, what about valve springs, are they all the same..........I have a 230 fork lift/industrial engine.......as far as I know internally they are the same as the car engines apart from maybe compression, but I'm replacing the pistons anyway.......but can anyone comment on the comparision between the car and industrial engines?........btw I'm in Australia and the 230's are not that common here so I am using what I could find, an ex airport tug 230, this is going in a P11 Coupe.......thanks andyd Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted September 25, 2008 Report Share Posted September 25, 2008 my 36-42 Plymouth book does not address this nor does the sister Dodge book for that year however the 46-54 are the same size..different years have different lash..this I would suspect is attributed to the higher compressions in the later years.. intake.....1 17/32 exhaust...1 13/32 Quote Link to comment Share on other sites More sharing options...
Andydodge Posted September 26, 2008 Author Report Share Posted September 26, 2008 Tim, thanks for the reply, what I was wanting to know was whether the actual valves, springs, and bearings were the same from 42-59, or ideally these parts are the same whether its a car 230 or an industrial 230, I've got 20 thou over pistons/rings lined up, but I can't find anything that says that the car/industrial 230 engine had any diferences apart from maybe those ancillaries that bolted on.......theres a guy in Turkey that has some good deals on these parts on ebay USA at present so that why I'm asking.........andyd Quote Link to comment Share on other sites More sharing options...

I've heard that some of them have gear drives instead of the timing chain, and that they turn backwards... You would have to confirm this with someone who actually knows what they are talking about... Pete Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted September 26, 2008 Report Share Posted September 26, 2008 spring rate changed a little later in production...would have to look that up again but is in the 46-54 Plymouth service manual Quote Link to comment Share on other sites More sharing options...

Plymouthy Adams Posted September 26, 2008 Report Share Posted September 26, 2008 reverse rev marines, is this applicable to single inboard outdrive setup or only where opposed twin engines were used?? Quote Link to comment Share on other sites More sharing options...
Andydodge Posted September 27, 2008 Author Report Share Posted September 27, 2008 My ex airport tug 230 uses a normal timing chain, I re measured the valves and they are the same head diameter as those listed for the car engines up to 59, the valve springs are the same length, ie 2", so that answers that one.......have decided to get the Turkish bits, he seems to have good feedback, so, Turkish Delight here I come........lol.............andyd Quote Link to comment Share on other sites More sharing options...
Tony WestOZ Posted September 28, 2008 Report Share Posted September 28, 2008 reverse rev marines, is this applicable to single inboard outdrive setup or only where opposed twin engines were used?? Generally in the case of single engine arrangements the engine is installed backwards and the gearbox (if fitted) and the prop shaft are driven off the front of the motor. Doing it this way the engine runs in the normal way. If twin engines are fitted then the engines are set up in the conventional fashion with cam and gear kits to run the engine in a counter rotating direction. Some twin setups have one engine rotating in the normal direction and one engine counter-rotating. I would not mind this one even without a boat.
