My Summit parts got here 2 days early!! Freaking love them! 
Started with the Throttle body seal. the O-ring groove was very deep on the intake...
So of course the seal isn't gonna do much good now is it!!
...
I don't have an LS7 gasket so I put some RTV in the groove instead to see if I can make the seal work...
And then put the O-ring in it...
I then put a bead of RTV on the back of the TB so with all that yummy goodness I hope that it seals...if not than I'll be running lean!!
Here's how she looks now...
Got it bolted up to the heads...Looks kinda mean on there!!
All I have left to do is finish cutting, fitting and assembling the fuel lines which is gonna take a little time because I don't have a Vice so I'm gonna have to go somwhere else to assemble them. After that it's belts, last of the wiring harness, new spark plugs, wire up the starter and download a tune and hope she doesn't blow up! Oh yeah, and I need to put the headers on!! The last of which should take me less than an hour...hopefully.

Ehhhhh... 
On second thought, I'm gonna run to the stealership tomorrow and see if I can't get a stock LS7 gasket...that 90mm TB seal isn't gonna do the trick and even if it does I ain't gonna feel good knowing it's in there like that.

Got a new TB seal at GM, it's the LS7 seal, I think this is what Edelbrock had originally designed this groove for! 
So off came the TB again!
Look ma no bolts!!
...
RTV didn't make too much of a mess, it actually woulda worked looking back but I'm glad I got the right one in it's place...
Spent about 30 minutes removing all the RTV from the flanges and then I stuck the new gasket in...like butter!!
And then torqued down the TB to 97 in/lbs and called that job done in my book!!

Sorry for not getting back sooner, been in China for a couple months and heading back tomorrow but she runs pretty good! Alot better considering it's a low compression 8.7:1 compression engine running without any boost. Numbers were 314/306 N/A. Same motor with a vic Jr on 18lbs made 730/743 or something, forgot exactly.

Ummm...nothing really on the truck itself. I drive it as a DD and scare the crap outta kids and women cuz it's so damn loud. The intake is performing awesome!!! Top end on the truck is a little outta character compared to the rest of the powerband, and I mean that in a good way. I did take it to the track and it did a 14 flat @ 103mph. As you can see the fact that this is such a low compression motor that I'm running N/A this thing has no low end but my trap speed is pretty good, at least good for mid to high 12's if it could actually get the truck off the line.
But aside from that I have a LSX TD sitting on my garage floor and I'm wondering what I'm gonna do with it!!
Other than that truck got rear-ended on the fwy and it's getting a whole new paint job, and this summer I'm either gonna rebuild the Forged 370 and add a turbo to it or build a 482ci monster N/A motor. Not sure what I'm gonna do. Whatever's cheaper really.

I am considering this intake on my LQ4 6.0 in my Datsun. Is the TB above or below the top of the alternator? Ask because my alternator is the limit of my hood clearence and if the TB is level or below the top of the alternator, I am good to go.
Thanks!!
Thanks!!

Looking through my photo-bucket account and found these two pictures, looks like it's a little higher than the alternator. You could always get a cowl hood no?

So I decided to take out the washers completely and put the bolts in without them...
The washers, unless I'm missing something are only there to add additional surface area to the clamping force of the bolt. Their not gonna keep the bolt from walking itself loose/keep the bolt tight. Regardless there was no other way to make the injectors fit so for now, this with a little loc-tight is the best way I can figure short of countersinking the brackets.
