My first "hot" car was a '71 Challenger with a built 340. I've also had a '68 GTS 340 auto and a '70 Swinger 340 4-speed w/ 3.55's and the rubber carpet.
That Swinger was bone stock and I remember being able to have it in 4th gear at about 35 MPH and it would pull cleanly all the way to redline, no clutching or anything.
My Challenger showed many a 454 and other big blocks the tail lights.
Love those 340's!
