Diy - Magnum Swap!!

This is exactly what I want for my 72 demon, thanks so much for the write up!

So, the only real "performance" mods it seems were the intake and carburetor, MSD ignition, and the HEI profile you selected?
Can you say how much a difference a mostly stock 360 did for overall power vs the /6?
Also, what kinda mileage do you get keeping your foot out of it?

Thx again, awesome writeup.
