If you do heads and cam youll also need exhaust if you dont right now(im sure you know that). You could of course run a custom cam with stock exhaust.
LS6 options
Super budget? Do a heads and cam kit from AI or someone else and run the stock ls6 intake. Youll see at least 430whp (around 500 crank) with supporting mods. 2.5k roughly
Or... Get some AFRs or trickflows, FAST intake make at least 450 rwhp. 4k roughly (Need roller rocker or knock off 400 if you shim the stockers)
I dont see the real advantage or buying a ls3 crate and sticking a cam in it over building the ls6. Cam'd ls3 will make 450-500rwhp. It will make more torque than the smaller ls6 but the lowest entry price is 6.5k on SDPC website. Used ones are cheaper, but you have no idea the true condition of a motor unless you know its history. Thats just for a stock motor. Add a cam kit and youre looking at 7.5k.
High end H/C/I LS6 build is at least 3k cheaper. The extra 20 or 30 torque isnt worth the extra 3.5k IMO.
These are just estimates,close but estimates. If you really want a crate motor with a supercharger I would go with the LSA crate engine from SDPC. Its 11k and will bolt up to your stock stuff. You will need a few things to run the gen 4 motor with your 411 pcm(gen 3), they around around 300 I believe.
Im pretty sure no matter what roots style blower you go with, youlll need to change hoods but I could be wrong. Hope that helps.
Im going with A&A supercharger myself. MPGS are great for the power, Keeps stock hood and with the right mods I dont have to worry about a C7z06.

Leaning toward the NA LS3 route, I've been looking into starting with a used L92, L9H, or similar truck sourced engine, but like you mention it's tough to know the true condition without breaking it down and possibly rebuilding (also, what's up with the VVT in some of these engines? Was VVT also in the auto camaro?). I'm also looking into the stroker LS3 option using said junker as a base, forking up the extra cash for the rotating assembly, having the heads ported, block machined, and building the motor myself... Sell the LS6 for whatever I can get to offset some of the cost.

Like others said.. modified or stock, unless your current engine is messed up... it's not worth the $ and effort to go Ls3 over your working Ls6. The power differential is not big, and the wet-sumped LS3 is well known to blow-up due to oil starvation issues more often than the ls6.

I like the extra cubes as well and prefer a less high-strung engine, but the LS6 has proven very durable. I currently have a mild cam in my LS6 and make 420/400...very enjoyable on the street. I took a step down from my 650rwhp Z28, but overall the Z06 is much more fun. IMHO, 500-525rwhp NA in the C5Z would be perfect.

When I was still NA, I'd gone to the expense of putting together a nice motor that had 483/432 without touching the block. It was strictly a street car, but had way more power than I have driver skills, and I supercharged it anyway. Whatever; you can do either with your LS6.

Build the LS6 as others have said. Will be cheaper and will easily mesh with the other components in your C5 Z06.
If the LS6 is worn or not reliable, then a LS3 crate performance motor is not a bad choice. An LS7 would be the best for track/street, but they are still on the high side in crate form.

Do some searches on the Road Racing Forum, and comeback.
The WetSump Ls2,Ls3 were complained about frequently by the SCCA racers, hence why GM ended up offering Dry-sump LS3's towards the end.
The Ls6 isn't without it's own issues (springs), but the bat-wing oil pan seemed to work better than the LS2/LS3 versions.

600+ all day. Some people are in the 700's but dont know how safe. Most in the 700's are running meth as well.

Building the top-end of the LS6 would probably keep me content for a few years, but only if it's designed for NA.
Building a LS3 based stroker on a junkyard shortblock with a modest top-end would cost a bit more, but would yield similar power, and would set me up with a solid base for much more power if I want to invest in it later.

Yup, understood. For a blower down the road I would be taking a different route vs NA. This is also why I've been looking at the LS3 as a base vs the LS6.

Like I said earlier, you could do a relatively budget 402 that would make an easy 500+rwhp for $8K and with forged internals, be ready for some forced induction, or a hit of nitrous. Heck Texas Speed has some 402s at retail for under $9K...
#39
Are you referring to a 402 on an iron 6.0 block? I didn't think the LS6 could be taken much farther than a 383 without being sleeved. I've seen that the iron block is a good base for a budget build, but the extra 100lbs on the front is what holds me back on it since I'm interested in spending a lot of track time with the car.
#40
Yeah, I often circle back to that option as I'm reading up on things and crunching numbers. I've seen used L92 and similar motors going for as little as $2500. Even if I only get $1500 for my LS6, I don't feel bad at all paying $1000-$1500 to start with a LS3 longblock.
