I am having trouble finding any kind of proformance parts for the 87 3.8 v6 in my cougar. If anyone has any suggestions on sites where I can find some it would be awesome.

Your best source (indeed, your only source) for performance parts for your Cougar is an 87-93 5.0 Mustang donor car. There is virtually zero aftermarket support for the CFI 3.8, so an engine swap is pretty much your only option...
2015 Mustang GT Premium - 5.0, 6-speed, Guard Green - too much awesome for one car

Basically it's:

Step 1: remove CFI 3.8
Step 2: install better engine of your choice
88 Thunderbird LX: 306, Edelbrock Performer heads, Comp 266HR cam, Edelbrock Performer RPM intake, bunch of other stuff.

Remove the CFI, I beleave a holly two barrel carb will bolt to the stock intake. Comp cams make performance cam for 3.8s and you can put newer mustang tubuler manifolds and dual exhaust. Or like everyone else has said, drop a v8 in. 302s and 351s have the same bellhousing as the 3.8 so just buy some v8 mounts and drop her in.
88 Cougar LS 5.0 .030 over, ported E7s with GT40 valves & trickflow springs, Proform roller rockers, HO cam, removed air silencer, K&N filter, smog pump delete, 2.25" dual flowmasters, Pacestter H-pipe & headers, HO computer, 65mm TB, Explorer intake, 19# injecters, 3.45s, rebuilt posi, and TCI shift kit.

^^^THIS, and TURBO. (low boost though) stock engine cannot handle more than 8psi MAX. Short of boost, though, yes - engine swap is your only real source for higher torque. Unfortunately.

And here is the place I got my roller rocker arms from, they're good and really easy to install.  They say you get about 18HP and 20lbs of torque from the 1:8:1 ratio.

Hooooly Geezus you paid almost $400 for a set of roller rockers????

334 bucks.  Yeah I know it was a bit much.  But you cant find them anywhere else for cheaper.

Yeah but you can buy 302 rockers and they work the same. And they're about 200 bucks cheaper. You just wind up with 4 extra rockers afterwards...;)

Builds are based on your budget and what you will use the car for.  Check my Car Domain for some V-6 ideas.
