I already have a set of long tube headman headers going into two 3 inch exhaust pipes feeding dual flowmaster mufflers.

Let us know how it goes. I have a Holley TB on my blazer so I did not modify the stock unit. Seems like a straight forward procedure though...

Well, last night I completed this project. I ended up getting a walbro 190ltr fuel pump, adjusting (and making) the fuel pressure regulator to allow 19psi of fuel to the TBI unit and plugging in the chip. The timing is set at 12* base. When I stomp on the gas it burns my 35x16 boggers. Off to Kansas City for a big competition tonight.
