I am currently considering taking out my 318 and putting in a 360. I understand the balancing and PCM issues, but I am wondering if I can still use the original exhaust manifolds and crossover pipe. I have tried several mods on the 318, but I still want more power. Any advise would be greatly appreciated!

 

Get a 5.9L Magnum and drop it in, done.

 

Everything will work. Exept for the flywheel and the harmonic ballancer. everything else will work. from stock motor mouts. stock exhast and intake manifolds. even the computer and injectors, and alt. ac everything!! Trust me I have done it. It is worth it.
