i found a 440 motor home motor with 30000 miles i can by. i am wondering if it will have to have work done on it to get decent power.i already have a 400 bb i can build that already has hp heads and manifold.its going in a 1ton 4wheel drive ram charger.

 

it'll need some stuff done to it
if you have a 400 already done, i would say go with that

 

the 400 will have to be rebuilt .the 440 runs but i read they are low hp whin they come out of motor homes. hate to buy it and still have to rebuild.plus did not know if 400 would make a stout motor.

 

curry -

Hate to ask the obvious, but what kind of "decent power" are you looking for???

curry - You are right about the power of the motorhome motors. They are a good base though for trucks that are being built how I believe you are building yours.

Give us the list of goodies that are in your Ram Charger (tranny, t-case(s), axles, tire size, gearing) and what you want for power. From there we can help you make the right decision on which motor to go with.

 

check it out really good some motor homes got the police interceptor 440 package so do checking first run numbers

 

sorry power went out last night. the rc will have dana 60 1 ton axles,4:11 gears now, plan to change to 3:77,maybe?auto trans. with devorce transfer case.plan to run 33 in tires.it will be ran in mud bog some , but keep street legal.

 

You could go either way on the motors. You could take the PH heads and mainfold off the 400 and throw it onto the 440.

The D60s are overkill for 33s unless you plan on going larger later. I'd leave the 4.11s in there too if that were the case.

 

78d200 is right on the money. D60's are overkill but you should not break them with 33's. not worth the money to change to higher gear. Why 33's? Mud bogs in Florida is over-run with tractor trucks, 33's would not go far.

 

My two cents worth, Go with the 440 using your HP heads,the manifold will not fit the 440. You need the torque of the longer stroked 440 to move that truck around. Stay with the 4.11 gears,as you will likely want a taller tire for any decent mud bog.
Good luck with the truck!
