The 340 is the biggest POS V8 Chrysler ever made.

Did anybody ever see a slow 340???????????????????????????????????

I have. Depends on the tuner. I watched a guy take a low 11 second Hemi over the course of a summer tuned it right into the 12.50's and he wasn't even ashamed of himself. He was a local engine build BTW. Nice guy though. Just couldn't tune.
