Re: 3.4 horsepower increase

I noticed a big difference when I swiss-cheesed the bottom of the stock air cleaner box on my LS1- Since then I have gone a step further, and added a true CAI.

+1 on the gears, I swapped out the 2.73 fuel economy gears my Z28 came with (along with the steel driveshaft that comes with those gears) for a 3.42 rear out of a manual F-body that had been wrecked. I would have liked to go even deeper, I was running 4.10's in my LT1-powered Caprice, and that was a hoot to drive. Would chirp third gear at about 75 MPH. If you change your axle, you will need to reprogram your PCM.
