Hey guys, I'm looking at building a 5.9 magnum motor for my barracuda and was wondering what the pros and cons might be and since I don't have the motor yet is there one year better than the next I should look for? It will be carbed so I know I need the intake but not sure what all else will have to be changed or modified and will 904 and 727 bolt up or do I have to go another route. Thanks for any info, Clay
