I'm starting my build of a 496. Due to finding a great deal on a block, I have gone with a 427 Tall Deck block.
It can hold a 4.375 crank without a problem, but I'll stay with a 4.25 stroke.
I am going to source a 4.25 crank, 6.8 rods, and 1.27 pistons.
1.27"piston pin height, + 6.8" rod length + 1/2 of 4.25" stroke(thats 2.125") equals 10.195" or .005 below the 10.2" deck on a tall deck block
thats a 1.6:1 rod/stroke ratio.
My question is that from my research, I can internally or externally balance this engine.
What are the pro's and con's of the balancing methods?
