BBC Engine Damper ???
 
Have another engine question – Not to make this to long of post but the motor I have appears to be a 468 with an aftermarket forged crank and H-Beam rods. When I started to tear the truck down and I removed the flywheel I noticed it had no external weight on it like a normal 454, once I found out that it had a aftermarket crank I assumed this was OK it was just an internally balanced assembly (I am only assuming this as I really don’t know how to tell???? The front damper looked weird to me also, but I just figured it was a smaller aftermarket damper BUT a buddy was over the other night and started looking at it and said it was just a stock damper that someone took the outer portion off of. The damper has no timing marks on the outside and also has no external weight?? He stated I need to get a new damper. Would I get a damper for an externally balanced motor? Or does it even matter???

I will post pics of the damper tonight when I get back to my home computer but any additional help before then would be great

Thanks guys

If you buy most aftermarket balancers the weights are removable - and yes I would use a non balanced unit if you believe your motor is internally balanced
I once had a big block that had the incorrect flex plate - it ran fine - everyone thought it should/would shake like crazy

Are the Summit brand dampers worth it or should I just get a TCI or Fluidamper?

Summit brand dampers are pretty good dampers, thats what were running on 1968SWBBigBlocks 454, not a single problem, not a fluiddamper person, they put out to many problems.

DO NOT use a fluid damper - the crank snouts on big blocks and fluid damper do not get along
