70" 340 vs 72" 340 specs please
Well if Chevy would had stop building the 350 back in 1974 like Chrysler did, Chevy would not be as strong today as it is.
Mopar drop the ball by keeping the 318 and ditching the 340, IMO
It could have went like Ford did and used smaller port heads for 2 bbl carbs and larger ports for 4 bbls, instead they design a great motor and ditched it after 5 short years, yeah the 318 - 360 shared many parts but the 360 was not built to rev and the 318 lack CI and the smaller bore shroud the intake valves
If the 340 would have been made till 1978 like the BBM were, there be many more blocks out there and more interest from the after market part companies. Mopar is to blame, they called it quits in the early 70's and the after market catered to Fords and Chevy's.
