What is the price for the ecotec extreme package, using the cam set up, and without the stroker kit?

I'm assuming you're referring to this package below:

If so and you don't already have higher ratio rockers or manifold spacers, then I would recommend the following 25mm manifold insulator 220 12mm plenum spacer 150 Comp Cam Stage 1-3 480 Double Row Timing Chain 165 Machined oil pump cover 77 Throttle Body 220 Ported Heads (Includes valve seals, springs, retainers, and collets) 1590 Depending on the parts you were after at once, we may be able to offer a discounted package price.NOTE: The mods above must be used in conjunction with a full custom tune and free-flowing exhaust system including extractors and high-flow cats. We can supply a cam.
