Heavier valves in the L92 and milder more torque cam for a truck in the L92.

I could be wrong, but isn't the L92 VVT and the LS3 not.

And the VVT.

Is the L92 easier to get used? Are there any differences in building up either of them? I was thinking of installing a L92 into this 70 Camaro if the deal goes through and was wondering how difficult the install will be. I planned on going through the L92 and going with a larger cam, nice set of heads and I really wanted to keep the EFI on it as well. Would it be easier to get an LS3 that already has decent HP and just install that? Sorry for all the questions, but I am trying to learn as much as I can.

Stock heads are great as is, add hardened push rods, car intake, ls7 cam, good valve springs, headers and you have 500 HP.

As stated the L-92 heads are great as is, but if it's an 07 change the valves they had problems with the stock valves breaking that year. Check with Mast Motorsports from cams/limiters to take advantage of the VVT.

I always thought LS3 + VVT = L99? What's the difference between the two?

DBW is the way to go.

How long have the OEM's been using DBW?

Other than Toyota trying to kill their customers, it's been good.

DBW has been treating me good so far in my DD. I will say that tuning it isn't as hard as I expected. It's nice not having to worry about the Idle air circuits, plus the PCM can easily modulate throttle so it can compensate for many drive-ability issues you see with a cable operated TB. You tell it desired air flow and it does the rest.
From an aesthetic standpoint; It also looks much nicer sitting in the engine bay.

The only issue I've ever had is a wiring issue caused my truck to go into limp home mode. It essentially sets the throttle at about 1500 regardless of pedal input. It's a little bit of an inconvenience, but a necessary evil. At least it lets you drive it back home.
If I didn't already have my PCM and harness I'd easily switch to DBW.
