Best for drag racing and if you don’t need an over drive then a built th400 is the ticket. If you want an over drive then a built 4L80E. The th400 is in theory better for drag racing because its weights less and has less rotational mass then the 4L80E.

I've never have heard of this one before. Normally turbo-350s are not known to take lots of power. Everyone I know that is making big horsepower numbers are running turbo-400s. If this company is willing to stand behind there claim and warranty the transmission if it breaks then this might be a good chose. If not then I still think a T-400 or 4L80E is your best bet.

That is definately not a typical 350. aftermarket case so it typical 350 rules won't apply to it. Never heard of it though.

I'm planning on a TH350 when I build my forged motor. Reverse manual valvebody and transbrake with a 4400+ converter on a 300 hp shot.

How will a built TH350 hold up to 800+ RWHP in a 3400 lb car? I want to run high 8's to low 9's when it is all said and done.

Would suggest the 4L80E for that
