hi guys, thought i should make this official. been a mopar guy for quite awhile, my grandpa and uncles fault. had a 71 340 duster back in the day (74-76) love those 340's! mine was an auto with 3.91's, put on a weiand exterminator with a 700 double pumper, but went back to the stock intake and thermo quad, big difference! will post pix if i can locate them. am really enjoying this forum, all my buddys were bow tie guys, so i had to pick up alot on my own. keep up the good work!
