snip Are the flywheels the same for the 3 and 4 hole balanced 304's? Jesse Snip Everything that I have on this type of thing says it is an "I don't care" situation. I am aware of a number of the larger cubic inch engines being swapped around so that you have to get the correct "3 or 4 hole" harmonic balancer on the engine in order for it to mate up with the existing pulley configuration. If there would have been a problem with flywheel/harmonic balancer compatibility problems should have shown up this way too!
