Default Anyone Use The Holley 58mm Throttle Body on 94-96 LTx?

I was about to order a Holley throttle body for my 95 and noticed the application only says Camaro and Firebird where other manufacturers list them for basically everything ltx from 94-97. Has anyone used one on their Corvette? If so, does anything need to be modified?

The key question is do you need it?
What mods do you have?

Well in case anyone has this question in the future, Holley says it does not work because the cam is different where the accelerator pedal hooks up.

holley 58mm is too small. i use the monoblade throttle body.

the asr throttle cam is too small which will result in a situation where you can adjust it ao that either:
a. it will not close fully but open wot fully
b. it will close fully but not open wot fully

the solution is to bend or modify the gas pedal upwards so that it sits higher off the floor and can pull a longer stroke of the throttle cable

good luck !
