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

most 340 A bodies would run mid to low 14's with a factory tune, skinny stock tires and a 3.23 gear. Most big blocks were the same with the tires of the day.
I think Ronnie Sox ran a well tuned factory 340 '71 'Cuda to a 13.99 at 100 flat.
..might have had a cheater slick, can't remember?
