mast motorsports l92 cam

[tinroof]

Anyone here have an L99 or L92 that they have done a mast motorsports cam swap on? I have an L92 in a my 69 C10, and I'm thinking of doing it. But I'm worried about all the downsides that come with the bigger cam. But, the way I understand it, the VVT advances the timing so you don't get the downsides. If I'm going to lose any bottom end torque, drivability, reliability, etc, then I'd just assume leave it alone. Anyone done it, have any experience swapping VVT cams? Any input....thanks
