Wow thats a funky UIM!

[ericjon262]

mars, will you check to see if that UIM bolts to a earlier LIM?

IIRC, the gen 4 intakes do NOT work with the gen 3/3.5 and earlier motors.

^true, it mounts via 8 bolts vs. 6. Not gonna fit older stuff. It looks very 3500ish.

[ericjon262]

thanks, just thought I would ask.

[SappySE107]

I have the adapters.

[ericjon262]

I'll start a new thread...

I wonder if the 3900 upper intake has the same bolt pattern as the 3500 did since i just sold a machined adapter for a 70mm 4.3 trottle body, Should of had my guy make a cad drawing of the adapter if it worked.

Um read above.

Sorry but Umm read my statement better i see where you got confused but im talking about the throttle body bolt pattern hence me using the term adapter.

[3400-95-Modified]

my bad

[alpinestar10]

Its all good. Relooking at that throttle body neck bolt pattern it is almost spot on i could be wrong though, Whats the opening on the 3900 75 or 70?

[CNCguy]

It is the same pattern but the LX9 pattern is on an angle while the LZs are straight. The LZs have a 75mm opening and the LSx TB matches up nicely with an adapter.

How cool would it be if the 2007 Montana manifold fits the engine bay of a third gen Camaro... NICE turbo header !!

[Mars]

Thought I would update this..

It does fit.
