I think the kit I have is an early LT1. Bob Weir makes kits for LS1 or LT1. Call him and ask what gear box and clutch type would be best for you. He has GREAT knowledge of his product. Proven quality stuff. It's not cheap. But in my opinion it is very much worth it.
The mufflers are the race series, not the street type. Yes I do run an aluminum flywheel.
