Im not sure which throttle body to by because the shop that is going to rebuild my lt1 said he has had problems with aftermarket throttle bodies sticking. he said he had problems with the bbk. can i get some help with choosing a good name brand that wont stick.

A stock T/B will support up to around 400 HP. So base your judgement on that.

I have the AS&M and it works like a charm. Never heard of anyone having a problem with one from them. They cost a little more but like most things you get what you pay for.

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.

That's not the problem we're talking about

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!
