I am buying from him in stages.

Next i will get the lower and then heads and cam.

Not going to install the upper right away just going to go ahead and start building it up

I'd do the upper just to see. It can't hurt!
it might even help more than you think
with a TB added on. At the higher RPMs
it will help for sure.

How big are the ports on the upper anyway? :-?

 

[RGR]

They are equalized at about 1.8 x 1.5 oval shape after hand porting.
Roughly equal to the 5.0 specs for a GT40 intake which is 1.65" round.
Those are widely recognized as being good to over 400 BHP (~425) which
means a well-ported CPI (single port) intake could support 300 HP on a V6.
