408 is up and running.....and it is bad ass....
Just got the 408 running. Installed the new LSXRT 102mm intake with LS7 90mm TB and FAST fuel rails. It looks great under the hood. Love to watch it "breath" when you rev the motor. It expands and contracts, so now I know what all the wrinkles in the cover are for....If anyone wants to know the details of how to fabricate the fuel system, let me know. There is a lot of work to be done after you get the manifold and fuel rails. Here are some pics. Will post some youtube videos of 0-140 MPH soon....this truck and motor turn heads at every stoplight...got to put some lower gears next. Shifts at 6200 now, but drops too many rpms after the shift. Will have the PCM retuned to shift at 6500.[ATTACH] [/ATTACH]
