That sounds like a great build idea! One of the things that really turned me on to TPI was drivability, which is one of the nebulous qualities people boast about when their setups don't make power, but it does really have a lot of low speed responsiveness because of just how early that manifold builds torque. My IROC-Z when fully warm will drop into overdrive going up a hill at 1200rpm and it's totally fine. Stab into the throttle at any time in any gear and the rpms come right up with a big smooth wave of torque. Which is sorta replaced by noise and disappointment by 5500rpm, but hey in a truck that's redline. It cruises awesome, basically, and the data supports it:

TPI makes a lot of power below 3000 rpm on a stockish 350, and you can feel that efficiency all the time.
That chart really doesn't woo me into wanting a TPI intake. Torque production at torque peak is great. True low end torque isn't really all that much better, and it all comes at a significant punch in the balls at the top end. That mini ram really is the best of both worlds on the stock engine.
