That's what I put in my '69 Barracuda and I love it. It's much better off the line, cruises (now) without that pesky drone sound and the gas mileage is great!! My car is much more fun and more enjoyable to drive. I'd do it again in a New York Minute!!
Somebody already posted a link to the "write up" I did when I was making all the modifications and for the installation. Also good tips on the 2004R mods/upgrades!!
