I've read lots of posts about which crank damper to use and everybody has thankfully shared their experience. I've got a 408 about ready and need to get a crank damper for it. Figure 95% track/5% street. I plan to limit the rpm to no more than 6600 rpm. Typical 408 build w/ Eddy heads and an Eagle 4" crank, solid flat cam, 10.5 CR, etc, etc. Should be in the ~500-ish hp range w/ a 3800 stall converter and a 3200# Demon.
I got the Trick Flow 19010 damper and about dropped it when it arrived! 13.5 pounds for that bad boy!! Not thinking I need all that weight 1) hanging on the front of the engine, and 2) having to be spun up at the track! Mancini has the PRP Pro Sport at 11.1 lbs and Jegs has their own #51640 listed at about 8.2 lbs (
JEGS 51640: Small Block Chrysler Harmonic Balancer/Damper Internal Balance | JEGS).
I've read how some don't want anything to do with a rubber sandwich-type damper but all these engines were produced with them and let's face it, these cars and engines are not being built to go 100k miles.
So I'm just looking to see if anyone has experience with either of these or a better idea?
Thx for the input as always!
