harmonic damper question

Yeah but if your spending $80, for $70 more--$150 there is Summit Bracket racing sfi damper, I got it. Very nice, the shining timing marks are hard to see, otherwise its great.

Mine in Internal, yours will still be external, why you should buy a damper that will last. Same with the flex plate, I know $ but you are paying for balancing and won't be able to do it again when the motors is back together.
