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

A 400 HP 318 would not be street friendly at all. Can a 400 HP 318 be built, yes but not by the average guy.
I'd be willing to bet most 340's and 360's on this forum aren't making 400.
FWIW my 383 powered 67 Fastback was running mid 11's at a buck 14 in 1980.
It was far from street friendly in race trim, it was my daily driver, I'd swap the cam and put on the slicks and go racing.
4.57 gear was good for the street and strip. lol

Just on the subject of 11 second street 318's...... Valiantracing right here on this site has an 11 second 318 Duster, no power adders (NOS or Boost), street car and races it in street form (or at least he did). I think he only had around .500 lift cam and edelbrock heads, ran off pump gas. I think he said it weighed around 3200 lbs ??? And yes, still stock stroke

Again, if you know what your doing and know how to tune.....
