[irishluck]

i also had one more question

i have a 73 dodge charger by the way

has the orignal 318 in it

im wanting to put a 440 in it

how would i go about do this?

You need a big block K-frame to start with and then a big block transmission or bell housing depending on if it's a standard or automatic. You'll also have to have the exhaust changed to match the big block. Those will probably be your biggest expenses.

Shumacher services offers conversion mounts noadays so Dumping in a 440 where a 318 was is a no brainer.....

I did that swap. Used Schumaker mounts. Eventually the 440 will break your 8 1/4 axle if you drive it hard. So 8 3/4 axle and new rear springs. BB radiator,accesory brakets, electronic distributor, driveshaft . Alot of little headaches.

I don't mean to hijack your thread irishluck but I have a question..

I will be doing a 318-440 swap in my 68 charger, will I need a new K-Member? or just new mounts?

just new engine brackets, your K frame is the same between small and big block.

Schumaker makes a addaptor spool type poly mounts that will seat a rb engine in a v8 (small block) k frame in the 73-73 Charger. Well made product . Does require alittle cutting and drilling on the drivers side of the k frame. $170

If you find a Big block k frame you can use the stock rubber spool mounts which are alittle smoother then poly. If you are going to do the front end rebuild the BB k frame might be a simpler choice.

73 and up k frames are different due to Chryslers Torsion Quiet Ride system.
