i have 3 BBC forged cranks that i'm sure are all the 366, 396, 427 variety but they are all a bit different. One is drilled through the front throw, one is not drilled and one is half drilled. One is a 6223 and the other is 622 with the last number missing and one is just 6 and no other numbers. Any help knowing what i have ?
The Word of God is quick and powerfull
All three cranks you have should have different counterweight shapes-profiles. I handpicked two 396-427 steel cranks awhile back. When I got them home, I looked them over side by side. I noticed both cranks had different counterweight shapes and thicknesses. One crank is 2 lbs lighter than the other. I don't really know what the actual application is for each crank. Hell, one might be a tall deck 427 crank. I'm gonna use them in a few 427 builds.
