340 440 swap

[Moparbob]

Hi,

I have a 73 charger Rallye with a 340 and I'm swapping it to a 440. I have a 440 with big block 727. I know I will need the big block mounts but will the transmission cross member and drive shaft still work?

driveshaft needs to be shortened(probably would just get a new one if it were me),upgrade front suspension components(or raise the tbars to compensate for the weight), bigger radiator, k frame should be the same(if i'm wrong, i will be corrected swiftly)


here's a hardware source

that's all i got to get the ball rolling.

let's see some pics.

Thanks,

I'm actually hoping the front comes down an inch or two Also,, you didnt specify about the cross member. BTW the radiator is plenty big enough. I'm running an external Tyranny cooler.

that's cause I wasn't sure on that one
I'm no engine guru, just wanted to get some info out there until the big guns come out and play today.

from factory diff between BB and SB cars are since 73:
-K member because slightly diff location on engine mounts, allmost unnapreciable... you save that with the shumachers engine mounts kits.

-inner pasesenger side fender does have a cut out on BB cars supposelly to have better access to something on engine bay apparently to replace spark plugs, getting more room to rachet and extension

-then on parts catalog it states apparently same T bars but diff sway bar.

and of course, radiator and rest of stuff already mentioned.

tranny K member and mount is the same

Neat,

I tried today to install a core block in the car (just to check) and yes it seems as though the engine needs to move back 1 3/8" as stated. Also I noticed it was slightly twisted in the engine bay, something Im sure the Shumakers address.

Two more questions however:

1. It appears the engine is slightly off center slightly to the passengers side. May I assume this is normal?

2. Headers,, What the heck! Seems like there is plenty of room on the passengers side but none on the drivers side. Can anyone recommend a lower priced set of headers that will work?

were you located?  i would love to swap my car back to a small block k-frame.  I swapped to big block back in the day, then built my own mounts to put small block back in (gas prices were killing me).  I don't trust my mounts to real power so i need the k-frame to put in the motor i want.  i'm in california.
