Today, dollar for dollar, is the 318 faster than the 340 ???

273 said
I bet there's two to three times or more people with 273/318 and never mind the /6 guy's have under there hoods than 340/360, If everyone yanked there 273/318 tomorrow a swapped in a 360 like the 360 crowd wants 360 would dry up and become big dollar. Most 273/318 guy's are looking for little gains basically tune, mild cam, 4bbl and duals and maybe headers yes a 360 would be slightly better but the mild hopped up 273/318 would be enough power for most.

You mean not everyone is a drag racer? (Sarcasm) We lived in our 64 and 67 Barracudas. Both 273's at different levels. Great real life stories that came from diving them all over the country for a couple of decades. Mine was able to run with cars with 100+ extra cu in. Still running 273's with a 340 on the stand, ready to go. No 360 or 5.9 in the stash, nor will there ever be.
