The 340 is the biggest POS V8 Chrysler ever made.

I can remember back to the 80's when I raced my all steel '71 Cuda 340, 727 s/strip car which was nothing much over stock, just well set up, with almost complete stock suspension apart from a snubber, it ran 12.4's@108, the 440 A/E body guys didn't like racing me when it was Heads Up for money.....cos 95% of the time they lost!!...
