318 to 440 engine swap
« on: October 13, 2010, 09:14:40 PM »
I have a 1982 Dodge Ramcharger, 727 tranny and a 318. It's 4WD and has the stock axles.
I've been trying to read up on other posts but can't seem to make heads or tails of them.
I'm in the process of purchasing a 440 engine and tranny out of an old motor home.
I basically need a list of things I need to do in order to successfully complete an engine swap.
Any help?

    If its a complete motor with carb and manifolds you really dont need anything. motor mounts, maybe some vaccume lines, and the radiator if the bottom hose of the water pump is in a different location. because its carburated and not fuel injected you wouldnt have to worry about all the new electrical censors and wiring. you might have to change out the exaust or maybe just the flanges so it will bolt up to the manifolds. but you should be able to get it in and running in a day. let me know how it works cause when i get the money together im going to do the same thing. I have an 86 RC with a 318 6" lift running on 35" MT's.

    You will need to address the fact the big block trans is 2wd and you're putting it into a 4wd... I don't think the motor mounts will work. But you may get lucky. You'll soon find out there are a ton of little things.

    Motorhome oilpans are usually front sump so you may need a pan/pickup tube/dipstick for a truck aswell as you will need motor mounts and you will have to lengthen the dist wires because its in the front. Also as stated youll need a diff tranny But if they are both lockup cnverters trannies you can have the guts swapped to make the bb trans 4wd and same for if they are non lockup but you cant mixed the 2.
