No sir a stock LS1 throttle body will not fit. Like stated by mbaker3 the LS1 tb has 3 bolts to mount instead of the 4 needed for that intake.

The FAST 92mm Throttle Body works great, but it is a little high $. I just purchase one to go on my LS3 intake with L92 heads.

Yeah, unfortunately there's no OEM one from GM that will work. You have to go aftermarket.

I just found a UMI 90 mm throttle body that is 4 bolt for $200 in new condition. You can find them but have to be really on the look out for them.

BBK has an off the shelf 92MM for the ls3 that retails for $319, I can give an LS1 tech discount if interested. It requires the reuse of stock TPS/IAC

hey MIKE shoot me a PM what one would cost shipped to watertown SD with shipping and LS1tech discount. I am also military if that helps.

right now I am leaning towards a NW 92 off ws6 store for 329 and probably prefer it over the BBK but if its a good enouph price Il get one from you.

I will have to probably have my mechanic order it for me though since i am still deployed overseas shoot me a PM

Do you need to change to a 24 tooth reluctor to use a cable TB? I'll need a TB for my ls3 intake and would like to go cable...

I have a Holley 90mm Cable one forsale with Sensors too, aswell as a GM L76 Intake, if interested PM me.

The L76 uses stock LS1 MAP, LS3 is a screw-in.

nick williams is a nice piece in my opinion make sure you order a bracket or fab one up... FYI L92 intake has the smaller 10mm map sensor port... same size as ls1 ls2 ls6... plus on the you may need a MAP extension depending on where your orininal sensor is. ls3/l92s work with a 4+ inch bore

I'm using one of these to put my ls1 tb on my ls3 intake. Already have my TV cable stuff set up or I'd just buy a new tb. Decent looking piece though I'm not sure it's worth $95. Supply and demand at work I suppose.
