I have an 02 truck intake, its 75mm, I found a guy with a SS intake and he says its 85mm, a little over 3 1/4" measured....doing a search on here all I found was the 75 stock and the TBlazer/ssr 90mm...so was there a 85?

 

if im not mistaken there all 78mm

 

75mm butterfly, 78mm inlet opening, thats why Im confused, he measured the opening and its 3 1/4", mine is only 3" , Im trying to get a part number but we are playing e-mail tag.

 

I would probably hand it to inaccurately reading a tape measure.

and 3 1/4 inches is 82.55mm, and everything on GM stuff is metric, and that just doesn't sound right.

 

that sounds right, he said its 3.25, so that would be a like you said, a 82.5mm opening, so the throttle blade would be 80mm, not 85.....???? I asked 4 times and he said its over 3". This is the number he sent me just now 25321788

 

85mm is roughly 3.346 in 90mm is 3.543 in.......

 

My SS intake is exactly the same truck intake and throttle body that all 4.8/5.3/6.0 came with for 03-07 classic Silverados. Many 8.1's even carry the same tb.

 

Nice Malibu man!!! That thing is cool! you need to post up a thread with pics and specs of your Swap! Cool stuff!

 

Forgive Julian. He has A.D.D.

 

And O.C.D, I mean more detailed and stuff with pictures of the swap...or am I really losing it here?
