Ls1 with 243 heads/ls6 cam
hey guys. I have an 02 camaro ss slp 6 spd car. Other then long tubes its a stock car. Can someone give me some information on ported 243 heads and ls6 cam. Anyone know about how much power i could pull out of an ls1 with this setup? I'm looking for 500 whp and hope to be able to boost the rest of the way there. I guess my question is is how far can cam and heads alone get me? Also is there an easier way other the spraying? I'm not a fan of nitrous. I'm kind of new at most of this so any information would be awesome! Thanks!

243 heads and cam basically makes it a factory LS6. So 405 at the crank.
You can go quite far NA. Depends on what you're wanting to spend. Easiest to just put the LS6 hardware in a boost it to 500.
If you truly want 500 rear wheel NA, it's both difficult and expensive on a 5.7L. There is a handful of us that have done it

Like mentioned above, 400+ crank Hp is what your looking at with 243 heads and LS6 Cam.
I would have a Cam Spec'd by one of our Sponsors or choose an aftermarket off the shelf cam over using a GM OEM Cam, especially if you are looking for 500 rwhp. The 243 heads are definitely the right choice if your looking for more usable power. Having the heads milled to bring you to 11:1+ Compression will give you a nice bump in power as well.
500 rwhp is around 570-590 Hp at the crank. As mentioned above by Darth, it can get expensive.
How I would do it is;
- TSP-PRC Stage 2.5 243 heads, mill them to put you at 11:1 Compression
- Custom Spec'd/Off-The-Shelf Cam using a Cam Motion 8620 Core (Example: TSP Torquer V2 232/234 .600/.660 112+2 LSA)
- BTR .660 Platinum Spring kit
- LS7 Lifters
- Tick Performance 5/16" x .105 Wall Pushrods
- Stock Rockers with CHE Bronze Bushings
- Cometic 3.910" Bore, 0.040" Thickness Head Gasket (Measure Piston out of Hole first to determine proper head gasket thickness for 0.035"-0.040" Quench
- LS6 intake
- 90mm Throttle Body
- 1-7/8" x 3" Longtubes with free flowing Cat-Back
- LS2 Timing Set with Dampener
- Melling 10295 Oil Pump
- ATI Damper
This setup will put you in the mid/high 400 rwhp Range. You Could always go more compression, Fully CNC'd Heads, LSXR Intake, but that is when it starts to get pricey like mentioned. Now, just my opinion on how I would do it on a budget.

I feel a fully ported stock TB is the best you can do with an LS6 intake because of the throat on the intake is only so big. Fully ported is about 78mm if i remember correctly and matches the throat perfectly so, installing a 90 on something that necks down doesnt do much, in my opinion. If my theory is wrong, someone let me know because I don't have dyno proof. I'd go aftermarket intake that's made for a 90 or larger if NA is the direction.

Yup there's a holy triangle of hot rodding. Price performance and dependable. Pick the two you want and sacrifice the third. You could argue comfort or DD also but I find those tend to go hand in hand with dependability.
If you want dependable 500 rwhp, out of a 346, it'll cost you. Either through a great FI kit or tremendous head cam intake. Lots of cheap turbo kits, but you want dependability.
I'm all NA personally. But if you're already considering boost, bolt the LS6 stuff on and boost it. LS6 cam is a good boost cam. Ported heads will do wonders for a boosted motor too. You'll make more power with less boost.

But it seems id have to go big cam and heads which hurt drivability. Plus the price was like the same. Thank you guys for sharing with me. Like I said I'm a noob at ls motors atm. But I'm learning fast.
