Derek came down today to get a set of LG longtubes installed and a Tune. We decided to go ahead and make a baseline pull no tuning before tearing it apart.

Here is the baseline 100% Stock!!!






After headers and tune to come....

Six hp at the crank. Under the new SAE certified standards, GM can't fudge the numbers. It's real.

Nice numbers, I made 428 429 but I have a Vararam and I had a
very strong fan blowing straight in the scoop, numbers dropped more than 10 without the fan!
