Just a couple points:

1. You don't have headers. Those are factory manifolds, and it'* a REALLY bad idea to wrap them. They're going to crack on you even worse than if they were left exposed. Try a DIY ceramic coat (not paint). Most header manufacturers and retailers will void a warranty if you wrap for this reason.

2. A 2.2" pulley is WAY too small for that setup, especially with stock heads. As the weather warms up, you're going to get mad KR if you don't already. I suggest going back up to a 2.5" pulley and you'll gain more in added timing.

Looks pretty good. I raced with a swapped (Series 2) Grand Am for a couple years out here at Woodburn dragstrip. He'* a member of PDXCGP.

Well, as of right now, I have driven it hard on a 75 degree day with no KR present with the 2.2. I do have headers that use the factory manifold flanges, they also have the factory heat shields clamped to them. My rear header appears to have a warped flange just a tad. I have a want ad on here right now for stock manifolds and a 2.5 pulley, and am trying to get rid of my extra 2.2, we'll see what happens... As of right now, everything is working awesome, belts are wearing fine too, still look new.

This is making me want to do a swap into my 85 Buick Somerset.

I'll trade you a stock 2.55" I have laying around for your extra 2.2". Let me know if you are interested. It'* got some marks on it from being removed, but doesn't affect its' use.

I was going to mention the header wrap too but Wren has that covered. The only other issue I see is the lack of a heat shield around your air intake

Very interesting concept though! The motor looks like its really squeezed in there tight.

What color are you going with when you paint it? Black would be cool, methinks. Or go with something a little less menacing like white or blue just for the sleeper look.

I wholeheartedly vote for a Chrysler K-car tan color for the exterior. All your trim should be coated in a wood texture. That, with the L67, should be nasty.

I say leave the outside the way it is for the ultimate sleeper. Maybe fix the front bumper a bit with some paint, touch it up a bit, etc. But leave it looking all stock on the outside. You'll have so much fun blowing the crap out of stupid ricers at the track. Heck, my car weighs a crap load more (and is stock) and still beats the crap out of most of the cars at the track.

Wow, what an amazing swap! I love the 3800 SI Grand Am swap, it looks terrific. I was hoping you could help me out with a potential swap. A buddy of mine is going to sell me a Bonneville with a very beat up body and wheels for $300, but it has a 3800 Series II. I own a '91 Grand Am. I understand that the car isn't the same as yours and the engine is far from it, but maybe you could give me some pointers?? I'm mainly confused about how to make the gauges communicate with the Bonneville computer, and what to do about the wiring harness. Please respond, and thanks for the help!
