I bought a car last year, and it already has quite a few mods. But, it has a reverse split cam. It supposedly makes slightly over 400rwhp N/A, but i havent had it on the dyno or to the track yet.

My question is. with my mods (listed below), do you think this cam would hold me back if i were to go with a set of heads, and/or a FAST? Or should i go with another cam?

Lid
Descreened MAF
Ported stock TB
Stock LS6 intake
Crower (I believe) 234/230 .602/.598 - 116 LSA (I believe)
Comp 918s
Pacesetter L/Ts
ORY
Resonator Catback
Performabuilt Level 2 w/4000 stall
Racetronix Plug and play Fuel pump
3.73s

Thanks for all the input!

Personally, I like the reverse split for street cars. I've got a friend with a 236/232 and it's a beast on the street. I'd recommend it for a dd car.

The LSA is a bit wide so it will be a 4000+cam
Question you should ask yourself is what are you trying to achieve?

See, I usualy spec RS cams for strong undercurve power, but that requires much tighter LSAs. Yours being wide takes away a bit of those benefits.

To benefit from your cam you have to increase compression, my advice would be flycut and 59/58cc heads (243s) and not any heads but like TEA 243 stage 2.

^ i am loving those heads more and more...do yuo happen to know the difference between the 2.5s and the 2.0s, seems the 2.0s have the same and better flow numbers at lower lift...wondering what the differences are that merit the price difference and flow numbers being different

For the price of those heads of the stage 2 heads at 1800 or the 2.5's for even more you could get TFS 220's as cast for 1700 and for a little more get some yella terra 1.7's. Is it worth getting the LS6 heads or will you be better off spending about 200 to 300 more and the roller rockers and the trick flows.

If you upgrade in the future to a bigger motor than you can use the same heads and get them ported. I think cnc'd 220's could be used on a 414 or a 427 and make good power.

check this out. $2,258.40 out the door without sales tax for a set of TEA 2.5 LS6 heads!!!! Maybe I'm reading something wrong so heres the link to the pricing breakdown right from the TEA website:http://www.totalengineairflow.com/pr....5/invoice.pdf

If I see what I think I'm seeing they pretty close in price to a AFR 205 or a TFS 215's, and with the AFR's you don't need the roller rockers. For that price you can get the TFS 220's and the roller rockers.

hmm interesting...i have tried to call them to figure it out but no luck yet...

I am pretty stoked to see what the Stage 2's do for me. The flow differences between the stg 2 and 2.5 aren't substantial. Even on the exhaust side the 2's still seem to flow very similar #'s. I never noticed that before.

Just got off the phone for the stage 2.0s they are $1320 with customer cores…and $1800 for no cores…they flow about the same…only difference is the 2.5s have a larger valve which causes for special machining…I was told the difference in the heads are minimal…

PREDATOR-Z

Yeap, 2.04 int valve on stage 2 and 2.055 on stage 2.5

She is fun isn't she?

Wait until the exhaust is done.

IMO $1800 is still pretty steep but not unreasonable, they might as well not even make a stage 2.5 for that much more money if the performance is that close.

What is the advantage to having a larger valve if they flow the same?

I'm sure there is more to it that flow numbers. But I don't know enough about heads to know exactly what that might be. I would like to know though.

Thanks for the suggestion. Im basically looking to optimize my car for straight line performance. Im not looking for a max effort setup, just something that i can drive to the track and run, say, 11.50s N/A and then where ever a 150 shot will take me after that.

I know alot of it has to do with rubber, and suspension, and i already have some suspension mods on the car and plan to change em up/upgrade some parts to get me where i want to be. I also plan on dropping some weight off the car to help me reach my goals.

PREDATOR-Z

11.5 NA are achievable with that cam with proper compression. As to nitrous, more than 100 shot will not yield desired results (not as efficient).
Properly done with heads and some weight removal you should hit 10s NA

Im not dead set on keeping this cam, so would you recommend a cam more suited to my app? I just wanted to see what i could do with my current setup.
