Nailhead Dual Quad TT

Hello all

This is a easy one was the 401-425 dual quad intake single or daul plane??

I need to know becauseI have this CRAZY idea of building a Dual Quad twin draw through turbo motor for the packard. Already have a complete vintage rotomaster draw through setup and i have my eye on putting together a second.

Any ideas??

thanks

 

All the ones I have seen were dual plane...Good luck

 

Thank -you MrNailhead!!

Anybody have any thoughts on my proposed set-up??? Has it been tried before?

All feedback is greatly welcomed.
