Crank weight & harmonic damper

ss wannabee · 03-28-2007, 04:33 PM

Just weighed my 283 Chev Super Stock crank with damper, bolt, and nut installed.....came up 53 lbs. Nothing 'trick' here....NO Honda stuff....damper is an older BHJ 6" steel unit....a bit heavy....Went that way because wasn't sure of stick or auto,,,,,Trying PG now.....how's my thinking?

I guess my question should read......how light or heavy should the damper be? My combo is pretty much stock stuff.....in PG mode it's an 8" converter with a stock-weight or little heavier SFI flex-plate....may try one of those heavier 'JW' wheels as well.....In stick mode, I've got a McLeod clutch with lowered base pressure......a sort of a 'poor man's' 'Soft-Lok'...with several flywheels ranging from 12 to 30 lbs......planning on running a Doug Nash trans....there are several around here....With all the parts swapping here, should I worry about the damper? BTW, running beefed stock rods and light....but not super-lite pistons. 1965 Chevelle wagon 283-220 hp. SS/N(A).

ss you really dont need much of a damper with a short stroke engine.
ATI 6" aluminum 2 ring would work fine.

Maybe it doesn't matter what's hanging on the far end of the crank? The damper's job is to handle the harmonics of the crankshaft? Thought there might be a tie-in to the relative weight of the flywheel or flex-plate and the damper on the other end.....Thanks for the response!
