Which Dampner should i use for my 383 stroker?

 

if its internally balanced, why dont you use your stock one?

 

What type of balance are you running, how much HP, and how much RPM? Do you want underdrive, standard?

 

you can use your stock one but the only problem that i had with my 383 stocker was that my crank had 2 keys on it so Chad from golen told me to chizel the first one out the shave a notch on the stock hub it self

 

its internal balanced n iam lookin to get 450 hp.so should i just go for the stocker

 

A 12-year old damper might be on its last legs.... we're starting to see more frequent problems with the rubber cracking. So it might not be a good idea to reuse an old one on a new engine.

You could get a new stocker, I think Pioneer also makes one for the LT1, ASP makes an integrated U/D pulley/damper. If you plan to run under 11.00 NHRA requires that you have an SFI-rated damper. ATI and Fluidampr make those, at about $400 a pop. Two schools of thought... either ATI sucks or Fluidampr sucks, depending on which engine builder you are talking to. I run the ATI. There is also a "Fluid Damper" (note the spelling difference) sold on eBay for about 1/2 of what a real Fluidampr sells for.... who knows how good the quality is though?

You can have the stock hub keyed..... a "must" with a blower and a good idea for any high HP application. The ATI and Fluidamprs are keyed.

 

For 450 hp and moderate RPM i would go with the ASP replacement underdrive setup. Its in the mid $100 range.
