Curious as to what throttle body I can use with the LS3 intake. I know the stock LS3's are "drive-by wire" rather than a cable. Can I use an LS2 throttle body?

Thanks.

LS2 are fly by wire. I used Edelbrock 92 mm which came with the IAC and TPS.

Couldn't you just use a nw or any other 90 mil throttle body. As long as its cable driven

I just used a cable driven PTM 102mm TB.

Any cable driven 90mm T body will work. I recommend that you clean up the entrance of the stock manifold. Mine had a lip and some rough ridges.

Just keep in mind you'll need to fabricate a bracket to hold that little plastic piece so you can adjust and hold your throttle cable in place....there was no such provision on the LS3 intake!

It should be on the dyno this week, but I'm not to sure I have the fuel system for the power I'm looking for. I have a single Walbro 255 and 60lb injectors. I'm hoping for around 650RWHP out of my TC78.

Highly doubt that your walbro is sufficient to feed this power level, maybe dual in tank setup or one external large aeromotive is what you require.

That's what I was thinking as well.
