Im going to be realistic with you, I don't mean to hurt your feelings but its a realistic opinion.
You didn't list your rear axle ratio. This is important. Most times "street/strip" means more rear gear, and an engine built to perform at those higher RPMs. If what you want is a rumpity-rump idle for boulevard cruising (which is perfectly fine in my opinion), you might actually have a truck that performs worse on the street than it does now. A generic RV-grind is fine for a street 327, especially with street friendly compression and unknown rear gears. No lumpy idle, but lots of bottom end for fun on the streets.
For me; personally, fun street cars are all about the midrange RPM. Something in a Comp Cams 262H type grind would do fine.
Bogie's 268H-type grind is going to idle more aggressively, but you really want to bump up the torque converter. I'd avoid the TCI and B&M budget ones. Call the guy at Freakshow in Abilene TX. He builds some VERY nice TC's for about $400.
Intake:
Performer RPM, Holley 300-36 (also known in the 90s as the Contender), Weiand Stealth. No reason to go to the chinese copy stuff, there are plenty of the above intakes available for the same price. I got a Contender for a few bucks from a pawnshop LOL.
List the casting number on the QJet intake; you may have a good one already and the QJ will support all the power that iron headed 327 will ever make and then some.
Some other thoughts not directly related to your question:
Get rid of the TH400. Best thing you can do. Not that its a bad transmission; but its HEAVY and it eats a lot of power. TH350 or 200-4r overdrive. You don't need dual 3" exhaust; in fact, you could run a single 3" with a GOOD Y-pipe, look more sneaky and perform great
Your 327 is like bringing a .38 revolver to a gun fight. You can work with it, but you have to be better with it. If you want to do this as right as you can without tearing down the block; Trade TH400 for TH350, Howards roller cam conversion, Pro-Filer or Jegs house-brand aluminum heads, Holley Contender/Performer RPM/Weiand Stealth, Holley 3310 carb or something similar from AED/BLP etc, good 2.5" exhaust, 3.73 rear and the appropriate torque converter. You'll also want to recurve your distributor.
You can do most of this using the heads you already have. If you have a GOOD Qjet intake, Id put the money into the roller cam conversion, some good rocker arms if your camel hump heads don't have any, and the torque converter. Step 2 would be the performance carb and intake. Step 3 would be quality aluminum heads, lightweight valvetrain.
Option 2: just get a Vortec crate motor, put in a roller cam, buy the vortec version of the intake you want and make better power, cheaper
