6.2 truck motor ? I have a 67 nova with a hole under the hood. I have found a 6.2 in a messed up 2008 Denali. I know nothing about these engines. So I am coming to the experts (little smoke there). Is this a good choice for the deuce? Also what is it a ls3 or lq4 or what I dont even know what to look up. Im not completely new to ls just completely new to these. Thanks guys

For most practical purposes it's an ls3 (at least if you plan to ditch all the vvt/ afm stuff) but since you can't say "It's from a vette" the price is way lower. I have one in my chevelle, can't think of reason not to buy one if you aren't going turbo.

I have one with 6L80 in my 51 ford truck. I love it. Stock has plenty of power runs great. Torque at all speeds. Maybe one day I will add a cam and springs but will keep VVT. It is a nice advancement. A new cam can add 100+'horse easy without losing much down low due to VVT. Mast Motorsports work there is very impressive.

I bought it for $2900 shipped with trans harness PCM all accessories, a radiator, gas pedal, trans and power steering coolers. It had about 150k miles on it n
Had to pay about 1k to convert the trans to 2WD. that included changing over the pump to the new style 6L80 pump, new seals and then changed the clutches and any steels.

truck Thanks guys I've been looking around here and this doesn't seem all that high. The heads are good and a intake and cam change it should be strong. I can buy a 6.0 for a grand but most for this price has over 100k miles and I am little afraid of them. I'm pretty sure I'm going ls just trying to get different options. I need to research the vvt I know nothing about it. Thanks much

I have a number of links with good information about VVT in my build thread. For instance, take a look at the two quotes below:
I'm (obviously) planning on keeping the VVT, and looking forward to what I can do with it... 
Although Godbold returned to this subject, it quickly became obvious that he had other ideas aching to burst out of his mind. Ideas that can be summed up in the initials VVT-that's variable valve timing to you and me. "The L92 truck motor is incredibly impressive, making 400 SAE corrected horsepower stock and 430 hp with headers," he began. "With one of our cams and the phaser limiter kit, we made 500 hp, and it did not lose power anywhere. It's a great cylinder head, then you add the variable valve timing. We start out by giving the smaller cams lots of advance, up to 10 degrees, then you can retard those about 16 degrees. With the larger cams, piston to valve is tighter on the intake so we go down to 5 degrees advance. These designs run best with a sweep curve of about 12-degree retard, which helps the engine carry at high rpm."
The whole thing is better. You can move the cam around in the motor. Say you do a NASCAR cam with a 110 LSA. You can run it at 102, 106, 110, and 114 centerlines and get an idea of how it responds. It may fill in a gap, 104, 108...look at torque curve...102 best torque, 114 best high-end power. Good teams look at the specific track, look at where the engine spends time. This is something that would have taken us a lot of time and four guys on the dyno, and analyzing data in the past. Then, after you do it, you have to compromise. With the cam phaser, you can advance or retard the cam centerline to the position it runs best at each rpm. That's cool, really cool. You can get a 60-plus horsepower gain, with no loss anywhere. You can have control of the cam timing by tweaking a curve in your ECU, just like typical electronic ignition timing. It's like going from points to coil-on-plug.

I just sold one for that price, and it was a BRAND NEW 2013 L92 complete with harness/ECU, Power steering + AC, and flywheel/starter.
$3800 is a bit too high for a used one with that many miles. About $1000 too high.

Where do you guys suggest to look for an L92 (or any LS engine)? After weeks/months of searching Car-Part, there are very few deals to be had there. Almost everything there appears to be overpriced, according to this forum.
I work for a salvage yard and the obvious place to look is where we get our cars from....Insurance auctions. I'm not sure what you have in your area but we have public auctions and dealer auctions. For the price they want for just the motor you should be able to find a whole vehicle, Then you pull everything you need and sell some parts and take what's left to a recycler. If done right you can recoup some of your money making it an even better deal.
