You might or might not run into starter to flywheel alignment issues. Also the heavier flywheel will rob a bit of horsepower. However in a non racing enviroment you most likely will never miss the lost horsepower.

Awwwhhh.. This is what I didnt want to hear..  Im already going from a 250 Desoto/Chrystler engine to a 218/230 Plymouth  Boat Anchor!..  lol Thanks Don

while I admit that the Plymouth is synonymous with the Mayflower, I do not recall any boat anchors coming into play..

Here are some pics of the two flywheels.  Connsidering the depth of the Desoto/Crystler Flywheel vs the Plymouth it looks like the teeth align at about the same distance from the starter mounting hole.   I just noticed that the Plymouth ring gear is a bit thinner than the Desoto.  I would love to use the desoto one because it seems to have more depth which Im assuming would make it less likely to grind.

 

Anyone know why one ring gear is thicker that the other.  Im going to mount them both using my desoto bell and starter and see which works best..

 

FYI;   Im not exaggerating, the Desoto one weights twice as much as the Plymouth!!!!

You have to measure from the crankshaft mounting surface, not the disc mounting surface to determine if the teeth engage at the same depth. Find something to set the crank side of the flywheel on, block of wood, chunk of metal, 3 or 4 sockets the same height, that will fit in the confines of the crank flange diameter and measure down to the surface of the bench or table and repeat with the other flywheel. That will give you the comparison numbers.

Hi Lloyd! I am doing same with 1940 truck bellhousing (1939 same) and 1949 dodge 230 c.i. crankshaft with 8 holes (.187 thicker flange).

In summary: I need to machine out where the starter mounts, to offset the .187 so the starter gear will line-up with the ring gear....the throw-out bearing 

pressure plate/clutch assy. will clear inside the bell housing? Vintage Power Wagon flywheel is still available as of today and I will buy that and ditch my 201 flywheel.

Sounds Like a Winner unless you have had any other problem?

Thanks, Richie
