be careful with aftermarket throttle bodies as the have been very problematic. you might look into ID Fuel injectors a those are the best on the market. What are your goals
Detroit Rocker Cams, 410's, Saleen Supercharger, afco dual heat exchanger, TCI torque convertor, stage 3 saleen supercharger, dual gt500 fuel pumps, SS Brake Lines, and Power Slot rotors, LCAS, Koni Adjustables, alpine touch screen, PA deep tranny pan, fluidyne radiator, dynotech DS

In my opinion, screw the intake manifold you should just go full shaker. You'd get much better gains. Also, +1 on TBs being sketch, I've seen lots of people have problems.

It's not a bad list if you are willing to trade significant low end torque loss for a modest HP gain at redline. Replace the BBK TB with a GT500 or FRPP TB for reliability and don't bother with bigger injectors. The factory injectors will supply all the fuel you need for a N/A build on the stock bottom end. Don't forget to make it exhale better too. Even shorty headers will help a little when you open up the intake that much.

Be aware, in CO you can expect significant torque loss below ~3500rpm. We just don't have the ambient barometric pressure to get any kind of intake velocity going into the cylinders. Look through my sig for a similar mod list. All of the items on your list are intended for high rpm HP. Great at the track, but not so much for a daily driver. I have posted my before and after dyno results a few times in the forum. My HP curve climbs all the way to redline, but I lost over 50ft/lbs below 3500. Fifth gear is virtually useless in my car.
