Olddaddy Posted October 29, 2007 Report Posted October 29, 2007 I'm building the 218 from my Plymouth using a Dodge crank and rods. I want to confirm I have 230 rods before assembling things. I am fairly certain, but really certain would be better. My understanding is that the 230 rod is shorter than the 218 rod. The rods I believe are from a 230 Dodge have the number 954408 on them. Can anyone confirm that number is 230 Dodge? Quote
Plymouthy Adams Posted October 29, 2007 Report Posted October 29, 2007 Charlie..would have to get the part number when I get home..230....stroker model..shorter throw on the crank..longer rod... Quote
Plymouthy Adams Posted October 29, 2007 Report Posted October 29, 2007 Dodge D24 parts book ..IPB 9-31-4 is part number 954376 for cylinders 1,3,5 and 954377 for cylinders 2,4,6 now...don't ask that next question...as the book does not elaborate... Quote
Olddaddy Posted October 30, 2007 Author Report Posted October 30, 2007 Well now, that makes things slightly better I suppose......I guess it will take a measurement to know for certain. Someone must know. Quote
Plymouthy Adams Posted October 30, 2007 Report Posted October 30, 2007 218 has 4.375 stroke.... 230 has 4.625 stroke the 1/4 inch longer rod is the 230..and my second book also states that the 1,3,5 rods are the same and 2,4,6 are the same as I posted earier... Quote
martybose Posted October 30, 2007 Report Posted October 30, 2007 I was under the impression that if you use a 230 crank, you also need to use a 230 flywheel, as the mounting bolts are different. Hope you got the flywheel with the crank! Marty Quote
claybill Posted October 31, 2007 Report Posted October 31, 2007 why would rods be different? odd vs even # locations. ? do they face different ways..? do rebuilders know this??!!!!!! bill Quote
Plymouthy Adams Posted October 31, 2007 Report Posted October 31, 2007 now dang it I told you when I first psoted that I did not want to hear the next question..WHY...was no explanation..if it were a V design it would be most obvious for sure... Quote
48mirage Posted October 31, 2007 Report Posted October 31, 2007 I'm beting there is an offset in the connecting rods. Jim Quote
Merle Coggins Posted October 31, 2007 Report Posted October 31, 2007 Yes, there is an offset on the rods. I found this out when I was putting my engine together. I went to put #1 piston in and it just wouln't go down onto the crank. After much fuming I finally realized that I had mistakenly grabbed the piston at the wrong end of the line. I had #6. There is just enough offset to the rods that the odds won't fit on the evens and vice-verse. Quote
Normspeed Posted November 1, 2007 Report Posted November 1, 2007 So Charlie, did all your rods have the same number on them? Quote
Guest P15-D24 Posted November 1, 2007 Report Posted November 1, 2007 That is the best way to ID them. Quote
