Internal or External balance 408???

BrianT,

My opinion, for what it's worth (not much probably), would be to pay to have it internally balanced. What's your total build cost, $6,000? That means $300 is equal to about 4% of your total cost. The internal balance gives you the freedom of not worrying about a specific harmonic dampener or flywheel/flexplate to keep the engine in balance. I had my 408 internally balanced and it cost me $225.

Here's a good overview of the process:
