So I was looking at throttle bodies today for the LS3 intake. It seems as if the new Holley sniper throttle body will fit an LS3 intake manifold if you need a cable driven throttle body. Am I wrong thinking this? If so a brand new throttle body from Holley for 180 bucks seems like a great deal considering a Nick Williams is close to 400

158 views and no answers? Looks like it might be a solid question. I tried Texas speed the phone dude didn't know. Ill try to get ahold of Holley today.

The 92mm holley sniper will fit the ls3 intake BUT you have to buy the holley iac with it. The stock gm wont work. So it turns a $179 tb into a $235 tb.
We have em on hand
The nick williams is $369 but higher quality and uses the stock iac motor. Still over $100 difference of course.

Oh rad perfect thank you for your answer. I will be purchasing a new IAC either way so thats still fine by me. Now you say the GM one wont work which is fine, but does the holley plug straight in to the harness?

Hello
I'm in the middle of a similar swap, in the instructions for the IAC, it says you have to swap the A and C wires on the plug for the IAC to work on the LS harness.
The stock IAC and the Holley IAC look very similar, what is the difference between them?

543 105 - Requires the wires to be swapped
543 34 - This one says direct replacement but also fits the Sniper TB

Thanks
Bill
