    update i did a bit of the painting will post pics when all the painting is done. including the steps of ceramicoat baking. the engine already has an egr delete im remapping the computer and im putting bigger injectors and a more efficient fuel rail. mainly though im doing cosmetic modifications to it. the goal is around 240-250 hp not too big of a gain when you consider its tops 220 stock. down the road it will see a procharger but not right now. and the reason i chose a dohc 3.4 over a 3800 is simply their less common and when built right can handle as much if not more power.

    i got most of the painting done. forgot to take a pic of the steps of ceramicoating but its not that hard just follow the can.

    heres how the engine looks now after paint.


    side view.


    back and trans.


    with the valve covers and intake plenum on. the valve cover ran so i have to respray it.


    with the old heat shield i got a new one but it was too dark to take a pic with it on.


    i especially like the way the exhaust came out.
