Cam only.. want more power 02 ss m6
Thunder racing 224/224 .563/.563 114 cam
ARH headers magnaflow catback w/ HFCs
Whisper intake w/ 85mm granitelli MAF
KNN filter
365 hp/36x tq
California smog legal tune
Whats my best bet for power adders?
Fast 92?
243s (ported or stock)?
Staying NA
No spray
I want to retune because the car smells very rich and the numbers seem lower than average. Maybe because the “smog legal” tune? Figured I’d do a few mods beforehand.

I can probably find a used fast 92 for around $700 or so and install it myself.
Heads are tricky because the cost of porting is a lot and not all porting is of the same quality which makes it difficult to just buy a used set of ported heads.
My exhaust is welded. Im not sure if it needs to be removed or just pushed aside for the removal/install. I’ve also never done a head swap so I might have to let a shop do it.
Labor is roughly $700 and the heads are about $1500 from TSP. So anywhere from $1500-2200 depending on if I do it myself.
Im trying to weigh out the cost vs gains per mod. Thanks I’m advance.

Do you know what the gains are like with either one on a small cam car?

I know some people are making low 400s to the wheel with BTR stage 3 and MS3 cams but I really enjoy the low end of this cam so I’d rather not go that route. Plus those cams produce a really obvious “I’m cammed” exhaust note that might attract the wrong kind of attention.

Thats impressive, I was thinking the gains from heads wouldn’t be as much with a smaller cam (requiring less air flow).

I was thinking about just picking up some PRC heads from Texas speed but I’m open to suggestions. The shops around town quoted me roughly $1000 to port and polish. The heads go for roughly $3-400. So it ends up costing around the same.

I'm running a set of stage 2.5 prc 243s and I love them. But in hindsight with the amount of money I put into them and the rest of the engine I wish I would have saved a little longer and gone with an aftermarket casting and a "larger" cam.

It would be nice if I could hit my goal with the 224 cam. I like the power band and driveability.

It’s not just the exhaust note. I like the way this cam makes power. It’s very linear and comes in somewhere around 2XXX rpms. That’s why I want to add power to my current setup.

Is it worth upgrading the heads with a stock LS6 intake? I'm thinking about PRC Stage 2.5 heads or some ported 243s, but I don't want to have to drop all the extra money for a better intake, throttle body and everything else that goes with swapping an intake.

Since you're in California keep the smaller cam and do some good heads.
The best bang for the buck is $1700 Trick Flow as cast 220's
If you can't upgrade the intake with the heads just do it later, and a FAST 92 will be plenty sufficient for it too. Did a build with a torquer v3, untouched 220's, and a FAST 92 and it did 432 through an unlocked 3600 stall. Would have easily been 450 with a stick car.

Sooo I would really like to get into boost but I don’t want to deal with forging internals because that can get expensive. It would be really nice to have a supercharged fbody.
