Back in 1973 my friend had a 67 440 RT basically stock 440 4spd headers 3.54 Dana and slicks. I recall its 1st pass at the track was a 14.57 I know it went faster but not much that I recall can the 340 take a 440 Yes I have done it dozens of times I also have lost against the same 440 traction driving skills and In one case I blew my clutch apart. I love to watch and participate in races that are close
