On the off chance that you get it figured out what you actually want; then, with your current combo,
First;
is
convertor and a free-flowing exhaust.
Check out this graph; even tho it might be similar to your low-compression 360, don't look at the absolute numbers. Instead look at the shape, and the percent differences.
If your current stall is 2000, then on this graph that looks like ~105hp
By 2800 it looks to be ~155hp;
So ; that is an increase of 50%!
where would you rather be?


There is no one single thing you can do to your engine, besides Supercharging, or race gears, that can give you this kind of off-the-line boost.
At ZERO to ~20mph, this is a performance increase similar to;
a cam one size (or maybe even two sizes) bigger,
WITH an accompanying compression boost to say 160psi,
AND headers.
AND a 4bbl/intake,
all wrapped up together.

Check out what happens at 3200 on this graph: Max torque is what happens.
If you stall your engine at or slightly lower than peak torque,yur gonna need;
bigger tires,
a SureGrip,
and some kind of pinion snubber to eliminate wheel-hop. Yes, even with 3.21s/ go back to post #8

But if in fact, all you want is a rumpidy-rump idle, then that was covered on page 1.
and specifically by Rumblefish.
But be advised, if that will be your only change, then prepare for nearly zero performance increase below ~20mpg, with a very real possibility of actually losing performance.
