The 09 heads and lifters are going to be the hot ticket coming up. The MDS transition really differs from car to car, but for the most part I have seen it be pretty seamless.

We will soon be able to run even bigger MDS friendly cams with the 09 MDS lifters.

I've got cars with our Econo heads, Sidewinder cam and a basic exhaust running 12.40's with traction and knocking down 26-29 mpg on the highway with MDS.

I've seen 13.1's from an 09 R/T with no major work.

These cars truly rock !
