Looking for some flywheel help with a 427 tall deck. The engine is about a
'67 or so and is replacing a 454 in a '75 K30 HD with a standard
transmission (3 speed w/creeper). What do I need for a flywheel on this
engine? From what the GM dealer says, the 427 was never offered in a light
truck - this one came out of a tandem axle grain truck. Is the 427
internally or externally balanced? If I need to give more information,
please let me know.
