VVT or Not?
So my ongoing saga continues. The harness I had made for the l92 swap did not come with the correct 5 pin plug for the cam sensor/ VVT solenoid. They did not run the extra 2 wires to the location for the VVT solenoid either.
I've been trying to read up on this and very confused. This will be a daily driver in a heavy 1972 suburban. I've heard VVT helps with low end torque/ high end horsepower, and about 10% fuel mileage gain. I know a lot of people run without VVT. -- Should I make them fix the harness (or more than likely me since I already installed it and its a pain to uninstall) for VVT, or is it really not that big of a deal after all? -- If I don't run VVT do I need to do anything special to the engine, or will the solenoid not being hooked up be all that needs to be done? -- Will the tuner be able to delete VVT without throwing error codes all the time? Thanks guys! Shawn Posted via Mobile Device

Re: VVT or Not?
My LY6 is/was a VVT motor. My custom harness was built to run w/o it. I changed to a Comp LSr non-VVT cam (also from 1 to 3 bolt), LS2 timing cover, LS2 cam gear, LS2 cam chain tensioner, etc to make the change. In the beginning I ran this motor carb'd so no ECM for the VVT and VVT is not really in its realm running high lift, longer duration cam's.
That said...........for your application I think I'd want the VVT capability for getting all the down low torque you can get. how to remedy...might be easier to add a small VVT harness to the existing. I think Mast is one of the leading aftermarket VVT related manufacturers.
