318 to big block conversion,,motor mounts, k frame

Is there a way to swap out a 318 for a 440 on a 70 challenger ?  Can this be done by changing the motor mounts only ?

yep, Transmission if an auto will also need to be changed

Thank you Brad, just what I was looking for.

Current setup is a 318 w/904 trans,   Going to a 440 w/727 trans.

Sounds great!    You will also need a driveshaft.

Thanks Brad. 
Might even swap in a Dana while I have it apart.

Good luck with the swap. You will wonder who kicked you in the a$$ when you put your foot in it with the 440. You will most likely have to confirm you have the 8-3/4 rear in it and a sure grip otherwise hard to take off at the lights when the law is beside ya!

Consider that you'll need a different rad to. Outlets are on opposite sides

if you are doing the Dana do it at the same time the driveshaft length is 1" shorter with the dana

Thanks guys. It keeps adding up. Lol. So much for just swapping in a 440.
