I am asking this because I like the new throttle body from Holley with the NOS fitting made into it and I want that for my TPI. I have only seen it for the LT1 so would it work?

 

I think they use the same 48mm tb. Someone wanna back me up on that?

The linkage is different, and also the LT1s dont have a vacuum port for the EGR.

It can be modified to work in a TPI with some work. I had a 58mm LT1 Tb on my L-98 a few years ago..

 

Yes, it'll work. Not a simple bolt on though even though the bolt pattern is exactly the same.
the linkage is differant and will require a LT1 throttle cable too. If you have an automatic you'll need a throttle body from a 1993 to get the TV cable hookup.

 

Another thing you need to keep in mind.... that throttle body will give you a dry nitrous shot meaning you take a very high risk of leaning the enging out if you don't compensate properly. With a wet nitrous system that requires a plate between the TB and plenum, there's a hookup on the plate for the Nitrous AND a fuel line so you have the proper mixture of fuel and Nitrous and don't have to worry so much about the engine leaning out during the shot.
