tb Not sure about the lt1. If it has a wet t body stock just be sure the replacement is wet also. Sticking is generaly caused by freezing around throttle blade. Systems run coolant through it to keep it warm until operating temp.

My BBK never stuck, but I bought it second hand and the original owner could've taken care of it if it did when it was new.
I would say, if you're only doing a heads/cam motor, you should just get the stock one that's been ported to 52/54mm (stock intake can support 54mm w/o porting).
If you're just having bolt ons, you don't need one. Hell, mine isn't even installed, even though it's in my sig!
