Huge increase in power with this crank! By J Thomas (May 12, 2014)
I swapped a 6.1 Hemi into my 70 Duster and it was fast, but I could not break into the 10s in the 1/4 mile so I decided to stroke the engine and build a 426. I am more than happy with the big boost in power and I can run 10.50s easily in the 1/4 now even in bad air.
Be aware that to use this crank you also have to get the matching rods and pistons which Campbell's gave me a good deal on too.
