the intakes are on most, 08-13 GM truck/van/suv,

Identify them by the number of bolts holding the throttle body on..

Old = 3 bolts
New = 4 bolts

There are four types on 4 bolt intakes.
Return.
Returnless fuel rail, get the correct one for your ride.
and Square port.
Electronic controlled throttle body and Cable throttle body.

Match the new one to your old intake minus the bolt pattern on throttle body.

 

I have a lm7 intake which part number or numbers or engines would work for my setup I'm going to put 243s on soon!

 

What year is your motor?

With a little creativity and plumbing, any cathedral port 08-13 manifold will work for you.

 

2001 year model

 

Your fuel system is return. I would buy any 4 bolt intake you want from a Trailblazer SS, 08+ 4.8/5.3, a C5 fuel filter and this throttle body:
GM GEN LS1 LS2 LS4 LS6 LS7 92MM INTAKE MANIFOLD THROTTLE BODY PLATE ASSEMBLY SL | eBay

 

My truck is an 01', I am using an intake from a 2011 truck. I used a C5 Corvette fuel filter and a C5 fuel tank hose to connect everything. I tried one of the china-bay TBs, didn't work out for me, ended up with a NW 92mm. Got a throttle cable bracket from SDPC that works well. There are pictures of everything in my project thread.

 

Why didnt the cable work for you? Curious because I own 2 of the cable TBs from ebay, but havent run a single one yet. What am I in for?
