I'm putting a GM 385 Fastburn into my '80 Vette with a Tremec 5 speed manual trans and a 3:08 rear gear. I have Sanderson Blockhugger headers that I am planning on putting AIR tubes on and pumping air into the header as did the factory system.

I then plan on using JETCOAT on the front 2 1/2" pipes to contain and carry as much heat as possible to the converters. This being done to keep the heat out of my interior by containing it inside the pipes and second hoping that it will provide a better cataylst burn in the converter for a cleaner system.

I was thinking that using an AIR injected converter would maybe be more efficent also. I plan on using a pair of converters and have a question or two.

First, am I on the right track?

Second, Would using the 3 way + AIR be the best way to go ?

Third, How much, and where to buy ? I've tried to contact carsound.com but their mailbox is full and won't accept any more mail.

Three-Way + Air
Reduction/Oxidation Converter
A Three-Way + Air converter performs the same functions as the Three-Way converter. It oxidizes and reduces. The difference is the addition of secondary air between the two internal catalyst substrates that improves the oxidation capabilities of the converter. The secondary air is pumped into the middle of the converter between two seperate catalyst coated ceramic substrates. The front ceramic performs the reduction and the back ceramic performs the oxydation. Its like having two converters in one.

NO2 REDUCES TO N2 and 02
HC, CO OXIDIZES TO H20 and CO2

Any Comments or suggestions? Thanks JIM
