Default Twin GT67's enough or go larger?????

I'm still continuing my 408 build and was curious if twin GT 67s would be enough or would it be wiser to go with a larger turbo.

The reason I ask is that I already have one 67 and can get another(matching) from a buddy cheap.

.81 a/r housings Aiming for the 700 to 750 range rwp... I'm pretty sure the
67's max at 750 so this may be a wasted thought

Sounds like it would work but the compressor side could be smaller.. 1500 or so hp worth of turbo to make 750 rwhp.

It's very possible to get 700-750whp from twin 67's. Think about it, twin t3/t4 turbos will support 1000hp and 67's are noticeably bigger than them.
