Opinions on engine rebuild options.
Opinions on engine rebuild options. My LS1 has 96k on it and has been cammed since 92,500. Just recently its started burning oil under WOT, not a huge trail of smoke but you can smell and see it. Valve stem seals were changed out when I did the cam. That being said, I've decided I want to yank it this Winter and freshen it up or swap something else into it. Car is a 00' Camaro M6, cam only, full bolt ons, LS6 intake. I'm not sure what I'd like to do, I am on somewhat of a budget so making a 383 out of the stock block is probably out of the question due to all of the supporting parts that would have to be purchased. I was thinking getting it freshened up with forged internals, beefing up the cam, good set of heads, and calling it a day. Pretty much I'd like everyones opinion. I'm gonna say my budget will be around $5000.
As of right now, no. It still has the stock 10 bolt, so after the rebuild a Moser 9" would be the next investment. However after that I would possibly consider nitrous, hence why I'd like forged internals
Yeah $1610 straight from TSP, however what is the approx cost of making everything else work around that? Obviously the block has to go to the shop, I know the fuel system will have to be beefed up. Can I get away with running a stroker on stock ported heads?

From what I've read, you can definitely "get away" with stock ported heads, especially if done by someone reputable (AI, TEA, WCCH, Livernois etc). While you won't make as much power as some high end aftermarket castings, you will still be better off than stock heads for sure.
What's the specs on the cam your running ?
Your going to have machine shop chargers just to add a bigger forged piston (3.903-3.905) so the extra cost to buy a 383 rotating assemly isn't going to up the price that much.

The cost of machine work is about $1k. Once you add in the bearings and assembly/blueprinting, you're more like $1500 or so + cost of the rotating assembly. So, it's still cheaper to do a 383 out of your block than buying a crate motor, but it'll eat a good chunk of your $5k budget.
Livernois, TEA, and AI all charge about the same to port your stock heads. AI can weld up your LS1 heads for more compression with their HCR option and it runs $1145 + valve springs (if needed - if you're running a 383, you can just select the pistons you want and run the standard port job for 995). I'd just have AI source you a cam if you go with them. They have a 234/242 114 on several different lobes. That'll make power and still drive decent in the 383. I'm partial to that profile as it's one of the most proven out there. They also have a 238/242 112 that would work in the 383 too.
Just keep your LS6 intake for now and exhaust. Down the road you can go with an off-the-shelf FAST 102 and TB and it'll pick up good power everywhere.
Injectors. Goto FIC and get some 42lbs reflowed Bosch injectors for $299. They provide the data for tuning, so make sure that's loaded into your ECM before you start up the car to avoid washing down the cylinders with gas. And grab a Racetronix pump + upgraded wiring harness for about $200.
If you do the work yourself, you'll be knocking on the door for 5k with that setup. And probably a solid 450-470rwhp and 440-450rwtq. The FAST would help both of those numbers. As would 1-7/8" headers if you don't have them.
