Horsepower progression
The title might be slightly misleading.
My goal was to create a thread that specified the progression from a stock, 350 HP Corvette to a heavily modified vehicle that produces over 500 BHP.
I know some of the basic mods, like, headers, intake, and exhaust system. After that, where do you go from there?
My LS1 is cammed and has all of these mods. If I don't want to get too serious or too expensive installing turbos or superchargers, what are my options?

With the mods listed above your pretty much at the point of making some serious/expensive decisions when it comes to your car, Bigger Displacement, Port and polished heads etc, problem is you will eventually get to a point of needing to beef up supporting mods to the engine/car before you know it or you might even already be there.

I agree with all of the above. You must make a decision about how far you want to go, and that usually comes down to how much you want to spend. Anything above the 500+ mark means drive train mods must be considered ( i.e. Clutch ) 700+ means really drive train work on the rear end!
I have to spend another $10,000 - 15,000 next year on transplanting a built 416 to acheive long term power levels and durability.
Once done, it's very easily to have dumped loads of money in these beautiful cars to have what most of us desire. It's a fine balancing act to perform, mod the current one or buy a new one. I'm going to have a tough time after spending loads of money on this one, and when the C7 comes out, buying one of those. I will see how that plays out in the next couple of years. You can't take your money with you or car, so I might as well enjoy them while I'm above the dirt.

I went from a stock auto. Now, I never dyno'd each and every time, so some are marked with an estimate(?).
Stock auto - 290rwhp(?)
Exhaust - 291rwhp(?)
Vararam - 305rwhp(?)
ECS tune - 331rwhp
3.42/3200 - 328rwhp
AR Headers - 350rwhp(?)
Supercharger - 501rwhp
That's basically only the performance mods and I didn't list suspension or wheel upgrades, but you get the idea. You can get to 500 at the wheels (about 600-620bhp) pretty easily. Past that you need to start doing a whole bunch of upgrades.
Easiest method to get to the 450rwhp level is add a supercharger. That one mod alone gets you there. Heads/cam also can easily get you to 400rwhp.

Just asked a similar question in "Tech". I was thinking this:
http://paceperformance.com/i-7739382...-shipping.html
With LS7 clutch. Plug and play, warranty and probably all in for less than $10k. Comments?

402 - 427 LS motor with H/C and enough header to breathe it!
Although a simple bolt on supercharger (A&A Supercharger Kit) will do everything you want and more and it is a true BOLT-ON!
Thanks,Matt

I agree, but the forced induction would be on top of a 14 y/o motor without forged internals. Figure I could sell the old motor for $3-4 and have a net cost around $6k+/-. And the idea of a 2 year warranty isn't bad.

You do not need Forged Internals to run a supercharger -
On a stock motor even with "AGE" and miles can safely run a supercharger easily and safely!
It's ONLY when someone gets greedy and ups Boost beyond 10 PSI on an OLD motor without doing anything else they get into trouble!
Bone stock LS1's with miles and much of nothing else will put down 500+ RWHP (safely) on 9- 10 PSI of Boost!
Thanks,Matt

You got it!
It's not like the motor decays or starts to rot due to age -
If you're above 150,000 miles then I would suggest having the bottom end freshened or get a low mile stocker!
My buddy on his stock '04 MN6 coupe put down 565 RWHP (with full exhaust of course)

and old LS1 might be worth what, $500-$2500( with trans and wiring harness) CHECK FLEA BAY
LS376/515 http://www.gmperformancemotor.com/parts/19244552.html
$7200
Even if you rebuilt, wild guess, but I think your looking at $10K Plus
Best of luck to you.

Check FLEA BAY.
I do feel your desire and pain
Evey time I look to build a full race motor, looking at $14K on the low side, upto $30+ plus
( still needs to be rebuilt every so many hours of use too )
I can by a whole Camaro ( used) GT2 race car for $30,000 with spare parts.
