Like Steve said, You certainly aren't alone. And if you didn't enjoy the build, there'd be a heap of parts on your local Craigslist to regret selling later. I am at 9 years, I think Zig is at TEN. Nice thing is if you DO get discouraged (believe me, it happens), you can walk away from it for awhile, and come back refreshed. What fun would it be if the project only took a few months? You certainly wouldn't have the "ownership" that you gain over years of working on something. And as far as intakes... Hot Rod Magazine did an LS "Intake Shootout", 20 different pieces, both OEM and aftermarket. LS1 Intake: least powerful of all the factory intakes. LS6 Intake: more power than the LS1 Truck Intake: Though the most affordable of all the factory offerings, the truck intake easily outperformed the LS1... and excelled at torque production, nearly matching the performance-oriented LS6. The average horsepower and torque production for the truck intake bested the LS1 and matched the high-powered LS6, making the truck intake a good choice for many applications. They are just butt-ugly (I have 3 of them- and they are ALL ugly!) TrailBlazer SS Intake: offered more power and torque everywhere... more torque than the truck intake and more power than the LS6, the TBSS offered the best of both worlds. 20 LS1 Intake Manifolds: Tested!
