this is a ported and polished throttle body with bump stop shaved, collant lines cut and capped, polished spring and screws. bought it for my truck but its got a camaro shaft on it so i went to switch them out(takes 5 mins) but my screws on my throttle blade stripped so i said the hell with i'm selling it...

 

Will it work on the 5.3l?

 

yes it will.

 

As long as it's has a cable and it's not the newer fly by wire...

 

price?

 

yes just swap in your blade shaft.
