Pretty sure I have a 2000+ 3400 TB from an Impala... PM me your ZIP and a fair offer (include shipping, I'll figure it out from here), I'll make sure I have it and can send or post a pic. PayPal? Or?

You might as well just buy a 65mm throttlebody? I have one looks nice and gained a bit from it!

the 65mm TCE tb bolts right up to a 3400 upper intake and would not require any major changes to the rest of the intake.

shoudnt. Just porting of the plenum, but not required.

Without porting, does the 65mm make the performance better or worse? Larger throat across the plate, but a seriously mis-matched passage into the plenum would create a lot of turbulence...
96B-Mike, it is buried in my shed, I'll try to get it out tomorrow for a pic, but I would appreciate a price-range from you (PM'ed is fine), just so I'm not wasting time getting it -the last member who wanted to buy one of my old Z-26 parts basically wanted me to give it to him for free by the time the shipping costs were deducted from his offer price.

It isn't made out of gold, but it isn't worthless to me either, so... It looks like Expedited shipping will run about $12.50, regular post maybe about ten bucks. Do you have a local yard you could get one from for cheaper?

Depends on other supporting mods... Honestly I don't think a 65mm TB helps anything unless you have exhaust and cam work done to the car... without those changes then the engine really doesn't benefit much...

My otherwise stock '95 Z-26 did get a little peppier after I swapped-in a complete 3400 intake and TB setup, but I don't see that going any bigger on the TB was going to really make any difference as it seemed like the intake was breathing about as well as the rest of the engine needed it to. and having that serious of a mis-match at the TB inlet just seems detrimental to me, one of the reasons I wasn't pushing too hard to make the Northstar's 76mm fit onto my GTU's M90 SuperCharger (although it almost does bolt on, the ECM needs to be tuned for it to work right). But I do believe 96B-Mike actually has a 3400 under the intake, so maybe he can get a tiny bit more from an un-matched 65mm, I just don't know how much.

well right now i do have a 3400 in my car, but i have a 3100 TB attached to it (i had a 3400TB and my "mechanic" was saying the 3400TB wouldnt work cause the throttle linkage wouldnt attach? *i honestly forgot what he said, i gotta ask him again*...and i ended up misplacing the 3400TB i had *long story*)
I do have time to go to a junkyard, but NO FUCKING TOOLS...ugh i hate that about me!! lol
