I was thinking the Dodge was a 218,Ply.201,could be wrong. One thing to consider is the 251 or 265 will be 2 inches longer.Your '37 eng.is 23 inches and the 251 and 265 are 25 inches,could run into a little problem on the mounts. Do you want to drag,take off fast or just curise faster. I have a '38 Dodge and installed a '56 Ply.crank and rods,bored .040 over and made a 234 ci out of the 218.That gave me all the power and torque I needed then I installed a T-5 5 speed manual O/D trans with a 273 camaro rear and its a real cruiser.

Hi Bo....yes the Plymouth is a 201,and I think the Canadian Dodges used the Plymouth block. Not 100% sure on this though.
Looking more for a cruiser,and I will have to trial and error the fit. may have to go to an electric fan,etc. That T-5 swap sounds interesting......

I looked at putting a 251 in my 37 & heres the deal - the 251/265 are 2 inches longer.
37 bell-housing will bolt to the larger motor so no need to alter the rear mounts - you cann't shift the motor back unless you want to cut your fire wall.So you have to shift the front mount chasis brackets forward on the chasis. You have to shift the radiater forward 2 inches which is where it gets tricky. The sway bar which sits on top of the chasis gets in the way. You cann't shift the sway bar to the bottom of the chasis as there is not enough room between the chasis & the springs. I think you can shift the radiater forward as far as you can & lean the top forward to clear the fan. The reason I say fan is I have my reservations about elect. fans on these motors. Convert your 4 blade fan to a 55-59 6 blade fan this improves cooling. It's not a difficult conversion, but not a weekend swap either.
I didn't make the swap in the end not because of difficulty but a 230 became available & I picked up an alloy head & 2 carb manifold for next to nothing. In previous posts you'll see the pros & cons of 230 vs 251/265. Either way hope this helps & good luck.

if you have a 201 it is not a dodge engine. plymouth had the 201 from 36 to 41. dodge had 218 from 36. crysler had a 241. i have a 218 1936 dodge engine in my 38 plymouth. i used the plymouth bell housing and trans. the combination was a perfect fit. i have a 56 dodge engine which is the same length as the 36, 25 inches. i hope this helps. good luck. bob
