Hi

I need a list of Trucks with 5.3L V8 Gen III Small Block that came without Airpump and with Electrical Trottel Control from factory. 4.8l will also do if it can be overbord to 4.030" (6.0L)

Oh, and being havier than a 82-92 Firebird/Camaro will be also good.

 

I think it's '03 and up on the drive by wire thottle, you'll need the pedal and control box as well ,but the 05's don't have the control box I think as well.

I never heard of the airpumps on the Gen III there is on EGR valve that can be removed!

The 5.3 and 4.8 can't be bored out that big with out sonic testing the blocks!

 

Looks like i confused Airpump and EGR.

ON the Overbore Thing: I saw blocks with 4.8 5.3 6.0 markings on the Back, with 4.8 5.3 and 6.0

 

The 4.8 and 5.3 are the same block stamped on the front and back and can be bored out to the LS1 pistion size. The 6.0 has its own block and most times can't be bored more than .60 .
