Default List for mods

Ok, i'll post up here what i've got so far, and what i'm looking at getting later, and you guys tell me if you'd do anything different on the last list.

What i've got for the engine-
396 LT4
-Forged 396 4-bolt main LT1 block
-AFR 227cc LT4 heads, with matching LT4 intake manifold
-AS&M Monoblade 58mm throttle body
-Custom grind cam, something like .254/.266 .622/.638 112 LSA
-All supporting pieces: 42# injectors, new opti, new MSD wires and 6AL ignition system with blaster coil and wiring harness, etc...

What i'm looking at getting here in a week or so -
-Tranny rebuilt with carbon kevlar blocker rings, new 3 gear, steel shift fork, billet aluminium keys
-9" rear with 3.73 gears
-LS1 aluminum driveshaft
-UMI DD SFC's
-UMI Adjustable torque arm with tunnel brace and driveshaft saftey loop built in
-Adjustable panhard bard
-Upper panhard bar with relocation kit
-Lowerings springs, not sure which ones, something like 1-2" drop
-New shocks, looking at something not too expensive

I've already got a non-adjustable panhard bar, and lower control arms for suspension, but not much else. What do you guys think of the current combo, and then complimented with those suspension parts? Also, if you would change anything in that second list, what would it be?

Damn sounds like a nice setup I would suggest a dynaspark instead of the opti so you wont have to deal with it again, why not 3.90 gears? and if you have long tubes that 1-2 drop will kill them so you should think about that.

I do have longtubes, they're dynatech with the removable collectors. And for the springs, I would probably end up only doing a 1-1.5" drop max, just to give it a better stance for auto-cross if I decide to do something like that.

The car will be used for weekend kinda stuff, and maybe to work and back during the week. Kinda depends on how it runs, and how much gas it goes through.

I've got an M6 that will be going with this little setup. Also, the LCA relocation brackets will either be part of the rear end that is coming, or i'll buy some seperately. This build has just taken so long, and has been so expensive, that it's hard to remember all the parts that have gone into it, and what's left to get.

The only issue I have with getting a Denny's, is the pricetag on those. If I recall, it's something like 800 for one, but I haven't looked in awhile. That would max out my budget, and then some, and i'd have to save even more for tires and registration stuff. I might get it, but it really depends on whether or not I have the extra for tires.

EDIT:: Looks like I was wrong, it's more of a $400 pricetag right now.
