Was looking a 440 with a 927 transmission? First question what is a 927? I always see them listed with 727 The 31 plymouth will have a boxed stock frame and ford style I beam suspension from lucky 7. Is this motor transmission too heavy for a light car? will it cause me steering problems I think a 440 weighs 650? Please let me know what you think Thanks Joe
No fenders to start but I have them! just trying too figure out a motor I have a chrysler hemi but needs total rebuilding and adapator for transmission$$$ can always swapit later want to run mopar but not shure on the big block set up
Joe, I'm glad you are staying all Mopar....the 440 should work fine. By the time you lose the iron intake and exhaust and all the rest, it should lighten up a little. I've got a 383 for my 34 Ply sedan....so keep us posted!
Im going to be running a 413 in my 29 dodge sedan. Behind it will be a a833. My frame consists of the front boxed portion of a model a frame and the rear will be 2x3. Depending on what your going to do with the car will determine how well it will fit. Mine will be raised and set back under the cowl quite a bit and will have cowl steering. Lots of options. I say do it and post pics! Mopar or no car!
A little info for ya, 454=675, 440=640, 350=575, 289/302=460, 318=525 so all the talk about a mopar being heaver is once again put to rest.
And the 1937-54 Mopar 6 flathead is about 600 pounds. Not sure what the motor in the 31 originally weighed.
The 440 is lighter then the Hemi, and about the same weight at the original flathead 6. Put the 440 in. Gene
If your car was a four, it wasn't that much lighter than the 6, so weight shoudln't be a major factor. Clearing the stock steering box if you keep it may be an interference point. the manifolds that turn up from the ports are a way to go, as is offsetting the engine to the pass side about 1.5 inch.
Go for the 440. Your frame boxed is a very stout piece far more substantial than the original rail materials used on the cars these motors came in. BUT.....your nice original firewall is going to have to go...you don't have enough room between the rad and the firewall so you will have to recess the firewall lots for clearance. Luckily with your choice of a 440 the distributor in in front so that will help the cause. These are neat cars , miss mine, but you may find it interesting welding anywhere on the body. Mine was weird steel that was real tricky to weld with the mig nothing like my ford which you can weld easily.
440! The issue won't be the weight, it will be the torque. Make sure the foundation (frame) is strong, and build it! Go with aluminum for as much as you can afford, and the weight will come down if that's a concern. Heads, intake, WP housing and WP are all available. You can get front cover and valve covers too, but I doubt you will save much weight there. Late model starter helps weight and fit, provided you can live without the good old gear reduction sound. The main thing is being able to package the big engine, exhaust, steering and a good radiator in there. Plan ahead!
