Cobalt987S is an unknown quantity at this point

I see that the 3.7L is built from the 3.4L but is the 4.1L built from the 3.4L also?

Will also be built out of the 3.4... We are really reinventing the "top" part of the engine and working with the stroke as well... it is not just a simple re-bore as the engine is not capable of that displacement without a near complete rethinking.

Any idea when the 3.7 and 4.1 motors will be ready?

After we send our car to excellence we will be installing our 3.7... I would say late april for the 3.7 and mid summer for the 4.1. The 4.1 will be for a client not our own shop car.
