I'm building a 427 Cobra replica that should weigh around 2,050 lbs wet powered by a H/C LS2. I'm then planning on putting the 243 take-off heads onto by 2001 M6 SS and installing a bigger cam.

Question is, do I use the M6 from the SS for the Cobra or the MN12? Should I keep the MN12 with the LS2 and use it in the Cobra or swap it onto the SS? Both cars are running 3.42 gears and the M6 has already been rebuilt with beefier internal peripherals so there's, theoretically, negligible difference between them strenght wise.

THANKS and Merry Christmas!!

The MM6 should be better suited for the lighter cobra.

Definately the MM6 . You will not need the lower gear ratio of the MN12 in that light of a car with that much power .

X2, the closer ratios will work better.
