    348 RWHP & 356 RWTQ .....w/PPC Headers >>>>

    Air lid & K&N, G-MAF, HPP-3, cut EGR tube, 6-sp, 3.23 gears
    12/20/02, 40 degrees, rain
    323 RWHP @ 53000rpm , 334 RWTQ @ 4600rpm

    After:
    70,000 miles
    Same mods except header system
    09/03/03, 75 degrees, overcast
    348 RWHP @ 5700rpm , 356 RWTQ @ 4600rpm

        Nice numbers GG. Do you have any good headers for the SS454 pickups, I'm about to jump in with a full dual 3" exhaust. I just grabbed the SLP 3" dual stainless cat-back system for cheap in their clearance section. Now I just need some good headers.

          Im sure I should already know this, but for laziness reasons, I don't really want to do a search

          Anyhow, do you have anything for LT1's yet?

            The air Temperature was 35* higher during the run with the headers too!! I wonder how much more HP/TQ you would have gotten if it was cooler outside?

              Excellent results....I'm looking forward to seeing how the LT-1 long tubes go. When the LT-1 headers do come out will they work with the stock Y-pipe?

                Jeff.... no, nothing for yer 454SS

                LT1 systems are in the prototyping stage, now.

                The LT1 system will use it's own unique y-pipe set-up, similar to the LS1 systems.

                I'm glad you noticed the temp difference. That's why I included it!

                Thanks,
