In my eyes the tunnel on the 3500 intake is a worse design...

Guess just me.

I'm with Woody on corners cut. There has always been room to make the plenum bigger(longer) and kill that near 90 degree turn on the rear cylinders.
Always wondered how the 3500 upper had better over all flow with a 180 degree turn.
Ah crap, about to start a pointless rant(or I already have). Costly, crazy custom intake anyone? Didn't think so.

You need a minimum of 19 lb FMS (more like a 20.5 lb in GM ratings) injectors if you run a good flowing 2.5" Mandrel bent DP and exhaust with 3400 manifolds as well as a 65mm Aurora TB with adapter. The AC compressor will bolt up if you are careful and use a spacer on the lower bolt. You will definately need a custom tune to run it reliably as well as prevent stalling issues when that big TB shuts quickly.
