lid
long tube headers
true duals out the back
CAI
ls6 intake or FAST intake
ported tb
ported ls6 heads/tfs 215/prc 215 *one of those
UD crank pulley
gears

ms3/ms4 or other large cam

Fast 92/92
Trick flow 215s
We have a custom 4" intake setup that will make the most power from lid to tb
Custom cam
tune (we have custom tuning options)
Higher quality ARH/Kooks headers
Really any exhaust you want. SLP LM or equivalent will work just as well as true duals and be less $$$ and less hassle
11.3: 1 cr and possibly some 390 gears and a stall or nice clutch
That will likely make the most power on pump gas and be fun fun fun.
We have all those options available.
If you are doing this on a budget, I would stay on that line and get 1-2 things at a time, but stay on one track. You will nearly always get what you pay for.

The 10 bolt may be the weak point, but it will really depend on if you expect on 5k clutch dumps. The manual trans setups alot harder on the rears than the autos seem to be. An upgrade to a 12 bolt would not be a bad idea, but you can possibly get along with a good set of motive gears and a rear girdle kit.
With what was normally listed, you could be around 440 rwhp conservatively. Before all the bashing starts and thread links, we always like to estimate conservatively so we can all be surprised when it makes more. The difference will be in the TQ you make with the higher quality parts and diff head, cam, exhaust designs.

Underdrive is the common mod, but an electric water pump, esp for the price, is prob the last mod people like to do due to possible problems with not knowing if it is working. Plus they usually get the wrong one lol. Just because it says race doesnt mean its good on the street. And the street version is quite a bit more $$$ too.

They are not KNOWN to, but if they do, you will likely not know until it is too late. We do not advertise the harness, but we can have one made as a fail safe to let you know.
I did not mean to give you the wrong idea. They are super high quality and the better part is you can color match them etc.

Well . . . ( This is intended to be funny )
Step 1 - Completely disassemble motor.
Step 2 - Discard all parts, except for engine block.
Step 3 - Remove $10,000 - $15,000 from your bank account.
Step 4 - Start shopping.
Step 5 - Regret steps 1-4, once your realize that a 408 LQ9 Stroker would have only cost about $800 more ( buy a new block from Summit or look at the LQ9 short-blocks from Texas Speed ), given you a lot more power, and would have been much more durable, while only adding about 60 lbs. to the car.
How much HP ? Right up to the point where the LS1 block fails or you run out of money !
LOL !

really not a bad idea..... 3500-4000 on mods to a stock ls1 block...or spend the same amount on a 408 stroker......
but then again you would still have to get new cylinder heads etc. or do those come completely assembled...ready to drop in
