Hello all, I am restoring a 1970 Barracuda that came with a 318 from the factory. I got it with a 440 six barrel. I also have a 69 Roadrunner that has a 426 Hemi. Both are 4 speed cars and both have headers. I would like to swap the engines. Put the 440-6 in the Roadrunner and the 426 Hemi in the Barracuda. Is this doable? Need all the help I can get. Thanks in advance for your advice.

 

What block does the RR have, does it have big block style mounts or the Hemi mounts?

 

believe the hemi mounts. I have to check and get back to you. thanks
