That intake makes most of its power in the higher rpms and would most definitely benefit from a larger tb. The smaller one will choke it off. There are a bunch of holley 102mm copies out there that are very affordable especially if you have a cable style. If its dbw then you need to spend the $$ on the NW as its your only option.
that cam is also far from ideal for that intake manifold, your leaving alot of power on the table
Thanks for the reply.
My valvetrain will spin to 7200. The rods are brand new, nothing fancy just summit parts that claim to be good for 7500.
As far as the cheap DBC TB's they are mostly all hit or miss on the QC side of things.
The Holley, Fast, and the like all get lots of bad reviews they have tuning and idle issues.
I did see a Nick Williams for 400 at the summit, but at that price, I don't know if ill be getting much over the ls6 I already have based on your comment about the cam.
The cam comment makes me think I should just stick with the LS6 I already have...
I don't know if the cam will make power past 7k. on the last motor it was in it fell off at 6800, I have dynos showing it, so I figured an intake might help extend that.
