03 Silverado 4.3 to 5.3 swap

[Carlos Lugo]

In the middle of a 4.3 to 5.3 swap on a RCSB 03 Silverado 
 

Donor: 05 Tahoe with LM7
 

running into a few problems, truck is DBC originally, Using Tahoe swap with harness and the Tahoe is DBW. So I’m assuming pedal will also need to be swapped. 
what is the recommend route to get it working? Would prefer to keep DBW to avoid the harness issue with TPS

 

Will I also need to replace the brake pedal since the truck is vacuum booster and the Tahoe uses a hydrobooster?

Move the pedal assembly and TAC module over and it should work.

 

The booster doesn't matter.

Thank you for the response, 

 would have to get a non powered pedal, Tahoe uses the adjustable pedal so I don’t wanna have that wiring issue.

Just make sure that the pedal you get is from like the same year.

 

The pedal and TAC modules did change over the years so you couldn't stick a 2003 pedal with a 2005 module.

 

I'm sure you could double check part numbers on stuff to make sure they are similar.
