Default Which ATI or BHJ balancer?

I am working on a turbo 383 LT1 with a Callies dragonslyer crank in it. Was told I should run either an ATI or a BHJ balancer on it by Callies. There are like 5 different part numbers for the Camaro/Firebird ATI pulley alone, I was wondering which one is the right one to get. Also, if it makes any difference I was going to run a dry sump system with a drive mandrel, or if anyone makes one an integral pulley. Let me know if anyone has any input. thanks.

There have been issues with the aluminum hub wearing on a street car. On a RACECAR like yours I would definitely use alum.

Same as what I got, make sure you the T40+ for the counter sunk and a T45+ or a 12 point depending on what pulling bolts they send you.

Call ATI for your specific application. You will need extra parts to drive a cog system for a dry sump. As, discussed, you want a steel hub for the street and an aluminum hub for a race car.

I don't know what brands, but some guys here have really had problems with underdrive balancers. Search around before you make a decision [search is your friend].

actually I do have a question, is there any way to get one of those awesome HTD hubs for an LT1? Cause, I have actually removed all of the accessories form the front, so the offset doesnt have to be LT1 specific other than to clear the opti...any ideas? thanks
