I have an HPP III for sale and I'm asking $150 + shipping. It is for the Vortec 4.3, 5.0, 5.7 and the 7.4L. The stickers, instruction book and cable are all here!! It was used for about 7mo and I sold the truck. PM me if interested.

Thanks,

James

 

Did you leave anything at all from the HPP3 in the truck? Anything at all?

Did you remove everything from the truck and return the HPP3 back to stock?

What year is it for? What is the part number?

Thanks.

 

I want to know too. I am looking for one for my 98.

 

I'm sorry!!!!! It's for a 1999 4.3, 5.0, 5.7 and 7.4L. I don't know if it will work for the 1998 or not. I returned the truck back to stock(everything!!!). Everything is saved on the HPP III as it came from the factory.
