LS3 engine Hi guys, I have a opportunity to buy a l99 engine from a 2010 Camaro, it has about 15000 miles on it and I can get it for 3500$. The only problem is, It's missing all of the exterior components like alternator, starter, coils and all the brackets. I was wondering if there is a kit I can buy that would complete the engine.
Apparently there was a fire in the intake and I happen to have one at home so that wouldn't be a problem.
Can anybody look at the pictures and guide me on what's missing and on what I should do?
Thanks!

I would pass on this one...
Fire in the intake also usually burns the oil off the cylinder walls on the cylinders that had intake valves open and causes rust in those cylinders... Doesn't happen all the time, but this is what I have seen on some other brands of engines with intake fires
Sorry for the bad news...
Usually, most yards treat engines with intake fires as pure core value only, not a running engine
Look at car-part.com and see how cheap L92's with intake fires are compared to the good running engines without fires
Also, if You aren't dead-set on getting an Aluminum block 6.2L, the LY6 6.0l has big L92-style heads and only VVT, not VVT/ DOD like the L99.
With a mild cam swap, You are making more power than an L99

even with the unknown miles i think youre better off. these motors last for a long time, theres a few people here with 400k on the 5.3 they bought online and the thing is still ticking fine for their swap.

I bought the 6.0L for 1200$ looks good the guy said it has 50 000 miles I have no proof of that but it did not look very old, no rust on the block and the aluminum looks like it can be clean easily.
I think the price is right even if it has more than 50K.
Now I just need to get it to 450 + HP... i'm thinking cam and???

Good deal, is it an LY6 with rectangle ports or an LQ4/LQ9?
Either way, depending on compression ratio, You are pretty much knocking on 500 crank HP with a good cam and headers and a tune

Well... What are your plans?
Big cam?
High stall converter and gears?
The 317's aren't bad and work great for boost, just don't flow what L92's can...
What is your intended use for the car/engine combo?
Ps- I have a set of cosmetic damaged L92 heads for sale with rockers for cheap...
Let me know if You are interested and I will cut You an even better deal to help You out.
A mild cam in the mid 220's intake and mid 230's @.050 with .580:.600 lifts, L92 heads milled .030, using .030 fel pro gaskets and a stock Lq4 shortblock checked for piston to valve clearance of course should net You somewhere north of 520hp with decent headers....
Do the same with 317 heads and a different, matched cam for the heads and You are looking at 450 HP I would think....

I am rebuilding my 68 Camaro it has a carburator all steel BBC (very heavy) i want my car to be a good daily driver I don't want to have an overly agressive cam. So the 500 hp number might be far fetched but anyway 'Ill take anything over 400.
How much do you want for your heads? And what is the "damage". If you have pics that would be great.

very cool car....
an LS engine will be 250+ lbs lighter than an all steel BBC, so that will make a huge performance and handling difference alone!
If You are going to go fuel injected and get a good tune, a mild cam in an L92 headed engine with 220/235 duration will still be very drivable and have a very mild lope but make 500+hp with headers and a little more compression than stock.... Even with a carburetor it will work great....
You will find that it will work beautifully with a 2200-2400 stall converter to really put You in the meaty part of the powerband, but, it is not so huge that it won't "work" with a stock, low stall converter even.
when talking about old small blocks and big blocks and that it takes absolutely huge cams and great heads just to make 500hp with a small block and good heads and a pretty big cam with a big block to make 500hp also........ these LS engines are amazing....
