    I have a set of stock headers off my 5.3. Not sure if they will help at all.

    That would be sweet, Ill have to ship I guess as I wont be going that far east just let me know how you want to do that, im currently calling all the speed shops here in town trying to find the manifolds but still no luck. And I am building the truck for class 1450, or 1500 for BITD, probably will only run sportsmans class since every little thing on the truck is so damn expensive except for the engine. It will be at the dunes A LOT while working out the bugs this fall.

    Well I found some f-body headers that look promising on E-bay for 180, supposedly all 304ss construction, not the best for headers, but for that price... So has anyone on here seen them or installed them or know anyone that has. Oh yeah, got my wiring harness in from Sand and Street performance plugged it in and fired right up couldnt be happier with the harness and the price was WAY CHEAPER than anything else Ive seen advertized. When I get the engine back in and the firewall finished Ill take pictures.

    Thumbs up

    Well I got the headers pretty damn nice for the price, too bad I had to cut off all the emissions bs and weld the holes back up since I am not willing to take the time to polish them back again. Anyways here are the pics of the headers after I finished modifying them and on the truck after I framed the firewall out.

    Ive been working on the truck a little the past couple of nights and am making progress on the firewall. I got all the steel patches 90% done lack a little welding yet, and am about 40% done with the removable panels.
