How does the VVT work out with the manual trans? We're putting a L92 into a K30 with a full manual TH400 and our engine guy didn't like running the VVT without the corresponding auto trans talking with it. I assume he didn't think the cam phasor could keep up with a manual shift.

Of course your manual shift is not the same as a full manual auto. Maybe the tiny bit of extra time to shift a manual is all the engine needs to move the cam?

Cool truck!
