Start with;K&N's high flow setup (P.s:I hate it)
100mm TSP MAF
102mm TB
102mm fast intake w/ aluminum Ls2 fuel rails
55lb. Fast injectors high/low impedance
Stock coil packs
227cc PRC CNC Ported Heads (2.06" intake/1.6"exh)
Ms4 cam 111*Lsa
CTS-V hyd. Liters
Comp cam 7.4" pushrods chromoly
Comp Cam trunion rocker arm
Slp headers to TSP x-pipe/moroso spiral flows all 3"
Ls6 high flow ported oil pump
Double roller timing chain
Stage 3+ spec clutch
Stage 2 T56 trans (just rebuilt, stock gearing tho)
Rebuilt & balanced aluminum driveshaft with 1350 yoke
Moser 9" 4.11s (Aluminum case 40 spline Detroit Locker)
Stock brakes
Stock Sus. w/ jegster TA, PHB & slp SFC

Yes 550wrhp is 402 territory, but it is also 383 @ 8000rpm territory. Fuel injection makes even the most radical race engines streetable imo. The recipe for this is big ports, big runners, 250+ duration, big headers. Most of which will need to be made custom since the ls1 does not have a history in things like circle track and stock car racing.

I agree with the others. 550 rwhp can be done but why do it with a small motor? The smaller the cubes the more high strung it's going to be, which requires high stall converters, or very high clutch dumping, along with alot of rearend gear to exploit it (4.56 or more), and alot of other expensive stuff to go with it besides the engine build. It starts to be a "not so friendly" car to drive unless you are really hard core.
I much rather prefer to make that power with bigger cubes, it's much more friendly on the street, doesn't require as much gear or converter to be happy, and will have a much more broad and usable torque curve.
If you are dead set on keeping the cubes small and this is going to be a frequently driven street car then I'd go with a power adder, (procharger, turbo) setup. You'll easily surpass your HP goal that way.

Eganslp You may have bought a really nice setup. but probly will not run close to what the TSP car is if that is what your thinking. That car is a full on drag car 2800 lbs raceweight mite be lighter. with a bad ass trans and RPM to the moon. But hell I wish I had what you bought lol

Well I hope so b/c I spent like 6400 $ on that engine setup!! I mean I know my race weight wouldn't be anywhere near their's but with that head/cam it's gotta put some good #'s down right? Has anyone reached 500rwhp n/a on a 346cu" before??? Well I hope so, I'd pretty upset if I didn't hit that mark!! That was the main reason I wanted to get a head and cam package. It said those heads alone make an extra 80hp and that cam is supposed to do 60to80hp and along with slp package that's 375hp so I was kinda hoping for around 515rwhp but I guess we'll wait & see.

LOL horsepower math doesn't work that way an NO heads will make 80rwhp or even fwhp. You might see 480 on a 346 with a GOOD SD tune and the rest of your setup optimized unless you find a happy dyno. Yes Pat G made 500+ on a 10 bolt with worked over AFR's, custom exhaust etc.. etc.. and ran 183mph in the Texas Mile and that motor was on such the ragged edge it subsequently blew up.....

Yeah they also use probly no P/S and electric water pump and a ported fast intake. I know Tony Mamo ported and 102 and it gained over the none ported. 460 to 490HP what I would think. But I hope you acheive 500 that would be awesome. If you made 480 rwhp and a properly set up car it will fly down the track for sure. dont get to caught up in number unless there from the track.

500 rwhp from a 346 naturally aspirated is a tall order. Especially from just a head and cam package without touching the bottom end.
It would take a ton of rpm to reach that goal with such a small motor. More rpm than the stock bottom end would take for very long. No way would I want to spin snap cap powdered metal rods and cast pistons that high.
It's like this,,,,,how much can you tolerate in a street car??
If you like wild camshafts of 260+ @ .050 duration numbers that would make very little vacuum in a 346, and would struggle to support power brakes, if you like very high rpms and the things that come with that like a ton of rear gear, big stall converters of 4500 or higher, very finicky to tune, probably be on the edge of pump gas as it is (more than likely race gas), and lighten the car to 3,000 lbs or less,,,,then the HP goal with a small naturally aspirated engine is probably right up your alley.
If you would rather have less camshaft, a broad torque curve that doesn't require much rear gear or much converter, less compression ratio that is more pump gas friendly, much less finicky and easy to tune, More vacuum for power brakes, then you'll want to build a larger motor for that HP goal, something in the 400-450+ cubic inch range.
I wouldn't get all caught up in dyno numbers, Dyno's are tuning tools and nothing more.

the tsp prc 227 heads with a patrick-g or eps cam ,should crack 550 rwhp.get a cam to maximize the head air flow.or talk to Tony Mamo and look at some afr 225 or bigger heads.

Doubt it. Tony Mamo's 383 Vette only hit 540rwhp with a set of his HEAVILY worked over AFR heads and FAST intake along with a big solid roller and an excellent exhaust setup.
383's in the LSx world rarely make the power they should for the investment. If you want a stroker, go with a 4" bore minimum. 550 "streetable" rwhp would be a stretch for engine 50ci larger.
As far as the TSP 346 car goes, it made around 510rwhp through a 5000+ stall torque converter. Who knows what compression, but they said it wasn't pump gas friendly. NOT a street car by anyone's standards.Last edited by Marc 85Z28; 11-11-2010 at 09:01 AM.

ASA stock cars ran LS1s. An 8000 rpm cam will have terrible street manners it's making all it's power above 4500rpm. As far as FI making radical engines streetable that depends on your definition of streetable. If all you want from a street car is something that will make a 20mi trip to the track or car show than yes that works.
