The 340 is the biggest POS V8 Chrysler ever made.

and I thought the 360 was a POS. lol Get Real Get Mopar ! a well tuned LT1 back in the day would trim a well tuned 340.
hell, a well tuned 302 in the Z28 would give the 340 a run for the money. but I still like the 340 out of the box.
Back in the day, I saw 340`s w/ the same thing done to them as 350 chevys, cams-heads - valve size-auto. trans-race gears- slicks- the 340 would whip the 350`s *** , on the dragstrip! You build them exactly the same everything the 340 will win!
