my buddy has a 98 Z28 that he totaled wednesday night. the insurance adjuster came today and assessed the damage at $8000. he had lower control arms and lowering springs on it whiich the adjuster said he mat\y remove as long as he sent the stock parts with the car. so after work we pulled the e-fans and tb for my truck.

what is the difference in tb size between his car and my 02 5.3?

 

does anyone know?

 

ok, so i found out that the 98 z28 tb is a 75mm, does anybody know what size the 02 5.3 tb is?

 

I'm pretty sure that the truck throttle bodies are 78mm...they may even have a different bolt pattern than an F-body tb...
