PT81PlymouthPickup Posted September 1 Report Share Posted September 1 Anyone know if a flywheel from a 1960s 230 cu. in. Mopar flathead would be the same or usable on the 39-47 Dodge and Plymouth pickups with 201, 218 engines? Quote Link to comment Share on other sites More sharing options...
Robert Harrison Posted September 1 Report Share Posted September 1 I cant tell you definitively I can tell you that there are two bolt patterns a 4 bolt and a 8 bolt and there are two sets of teeth on the flywheels. I did find a 4 bolt on a 218 inch engine I had and it was a little lighter weight and I wanted to use it so I re-drilled it to match the 8 bolt by bolting them together and using a drill press and small set of bushing like I think they were bearing push guides from Harbor freight.

lostviking Posted September 1 Report Share Posted September 1 The 218 flywheel and the 230 have different offsets, so you might have trouble. I'm not sure, but I think it is because the crank flange is different. That seems to be like your starter and bell won't be correct. Hopefully someone with more knowledge will chime in.

JBNeal Posted September 1 Report Share Posted September 1 I believe the 12 volt flatheads had a different flywheel than the 6 volt flatheads in number of teeth on the ring gear, there may be an issue of the different flywheels having different planes for the ring gear itself, so starter engagement could be an issue. 1 Quote Link to comment Share on other sites More sharing options...
PT81PlymouthPickup Posted September 1 Author Report Share Posted September 1 Yeah! I was aware of the different tooth count. The ring gear on the 230 has 172. Can't remember the number on the one in my truck. Pretty sure it has less teeth. I was unaware of the offset. Sounds like I better look for one for the 201 and 218 engines.

The Oil Soup Posted September 3 Report Share Posted September 3 I believe the crank flange sets slightly further back on the 230 and the mounting pad on the bellhousing may need to be machined 0.180” to compensate for the starter reaching the ring gear.
