Build a STOP on the bracket to stop it from moving. A leg down on the back side of the intake manifold (on the bracket) for that throttle linkage.... It will NOT stay in place otherwise - I don't care how much you tighten it down. Not to mention over torquing the TB on the manifold... The TPS (Throttle Position Sensor) is very sensitive to the throttle position.

Won't take much to make a stop on the bottom side of that bracket - which was very clever BTW!

I had thought about that actually and then decided I didn't need it. I put a star washer between the throttle body hole and bracket to keep it from rotating. Seems great, but there will be a lot of cycles on that connection. With a heavy foot. So it is probably good advice, a little stop would leave no doubt...and it's easier to do now than redo after powder coat later. I'll do it once the engine is back out and easier to get to.

Your doing a nice job , I like the fender vents.

I see it's been a long time here since I've updated, but I've also been neglecting it pretty badly...so bad that all the picture links died! But I have resumed work on it, and it's moving forward again.

I got most of my plywood front & side splitters done, and my rear diffuser is glued & screwed...so the only thing left for them is some resin and filler work.

I made a rear hitch that looks like it'll work really well.

And I designed some caliper brackets to make rear C6 Z06 rotors and base calipers work with S10 Blazer backing plates on any old 8.2/8.5 or even 7.5 rear axle. You can even switch back & forth with 11.6 Blazer stuff to use 15" drag wheels.

My updates are basically in video form now on my youtube channel Gearhead Dezign. Check it out if you're interested.

Glad to know you're still working on the car!

Yeah I get too ambitious. Too many projects (6) and not enough time (dad now). Still writing checks my free time can't cash! 13 years into this Camaro now...about 5 wasted waiting for a painter who ultimately declined...but that's still 8 years to get probably 3 years worth of work done.

If you go on youtube you can explore:
96 Beretta "T56" FWD to RWD LS project
2dr Blazer "Z69"s: one Gambler 500 beater, one 5spd swap winter daily and one 5.3/SM465/SAS on 37s
01 Silverado "ZF6" 8.1 6spd manual
06 Suburban needing NV4500 swap

There's always something that needs to be done on...nearly all of them.
