throttle body not 3 bolt i replaced my thermostat with a 180* the other day and noticed that my throttle body was a 4 bolt instead of a 3 bolt. i was wantin to get the new weiand intake when it comes and that would be great if i didn't have to replace the tb at first. should my 4 bolt tb hook up? which tb do i exactly have, i couldn't find it online anywhere. GM part number: 19906F2030. thanks in advance

does anyone know what our stock throttle body size is (mm)? thats i 3 bolt i believe. somehow i have a 4-bolt. i'm guessing the same as the 4.2L trailblazer or 5.3L trucks. what are the sizes of the throttle bodies on a trailblazer or 5.3 truck? just wondering because i want the new weiand intake if it ever comes out
Search, search, search. We all have a 4 bolt tb. They are the same as the 4.2L inline 6 cyl. tb on trailblazer/envoys. Last time I post it. As far as this intake for LS4's and adapters and blah blah blah... I guess we'll see it like when diaBLOWShite has trans support. I e-mailed weiand about this so called LS4 intake and guess what....no reply. Big surprise, I doubt its being made for our cars. But hey, what do I know. Think you need to read the fine print.

the weiand intake isn't made especially for the ls4. its for all ls engines. i know some modifications will have to be made. i was just wanting to get the intake at first and not having to spend an extra 400 bucks on a throttle body

and our stock t-stats are 187*... so you're not gaining much, if anything, with that swap...
