lt1 383stroke. 153 or 168 tooth flywheel?
 

Do i need 153 tooth or a 168 tooth flywheel?

I already have an externally balanced crank/rods/pistons

Also Anything special i should know about the front end balancer? I know it needs to be one compatible with a 3.75 stroke crank but anything else?

The piece on the front of an LT1 should a neutral balanced harmonic damper. Not a balancer.

If your rotating assembly is externally balanced, they should have balanced it based on the standard balance weight on an LT1 flywheel or flexplate. Probably would have been a good idea to provide them with the flywheel.

Might be worth checking with the shop that balanced it.

Well it hasnt been balanced yet because im planing on bringing the flywheel and dampner with me to have it balanced. Can i use the syock flywheel or stock dampner with the 383 crank?

I was under the impression that when you stroke a 350 they use the flexplate and dampner when balancing the engine because a 400 crank is externally balanced

Stock LT1 flywheel has 153 teeth.

You don't stroke an LT1 with a 400 crankshaft - they are all 2-piece RMS since they date back to 1980 at the latest. You stroke it with an aftermarket crank with a 1-piece RMS, unless you want to go to the trouble of installing a 2-piece RMS adapter in your LT1 block. A stock LT1 rotating assembly is set up with the neutral balance damper on the front, and a weight flywheel or flexplate on the back. Are you sure your engine is externally balanced? Many stroker builds are done using internal balance.
