67' 318 crank in a 69' 340

Stroke it out to the max with a forged crank. Cast cranks are for mail box posts. :rolleyes:
This could very well be the dumbest thing I've read all year.
I've been building engines from Top Fuel down for 40 years.
Under 600 or so horsepower, there is zero benefit to running forged over cast in a Mopar.
Junk cast cranks are a Ford/Chevy thing.
