The 340 is the biggest POS V8 Chrysler ever made.

Speaking of a hemi and 455 buick stage 2. Back in the late 60's my dad worked @ a chrysler dealer as a line mechanic. He just finished doing a tune up on a 1966 or 67 hemi charger. He went on a road test and came up against the "mighty" buick 455 stage 2. My dad said oh what the heck!! Nailed the throttle and the Buick was just a image on the rear view mirror! Buick didn't stand a chance!! So hemi was/is superior to the 455 stage 2!!
