what is your combo?

Yeah hopefully...I'd be really happy with 320rwhp.

my cam is probably too small though. Here is my combo:

Flowmasters 2 chambers
K&N CAI
Eibach Springs
BBK Headers
Bassani X-pipe w/hi flow cats
Pro-M 75mm Bullet
Pulleys
Transgo Shiftkit
TFS street upper and lower intake
BBK 70mm Throttle Body
TFS twisted wedge heads
FMS roller rockers
Lunati cam L51014
FMS 24lbs injectors
BBK 190lph fuel pump
BBK fuel pressure regulator
Tru-Trac posi
FMS aluminum driveshaft
Flex-a-lite tranny cooler
4:10 FMS Gears
Crane Hi6 Ingition and coil
PI Stallion 3000 converter

Here are the specs on the cam:

RPMS 2500-6000

Duration In/Exh 284° 292°

@.050 In/Exh 218°/226°

@ Valve In/Exh .500"/.510"

@ Lobe In/Exh .312"/.318"

112° Sep 108° Int C/L

I'll probably get a custom cam one day that's bigger yet still street legal but for now this one will have to do.

forgot to add that it is now a 331 with all forged internals...

Posted by Glenn (Member # 520) on :
 
you should see 320 to the wheels, let me know how it goes.
 

---

Posted by twstd50 (Member # 1981) on :
 
Well the numbers were much better but no as good as was hoping for:

263rwhp
331rwtq

Byron suggested I get an F cam....

I have a cam for you, an XE274HR that should wake your combo up. $150.

Byron doesn't know cams. He knows how to tune.

If you're looking for 320RW here's ONE way it can be done:

1. Port the headers!
2. Ditch the cats
3. RPM intake
4. X cam retarded 4 degrees

Glenn- what are the specs on the XE274HR...

Can I pass smog with this cam?

Albert- Yeah I was glad to see the tq increase...it went up from 251 to 331 which is cool.

The PAW sells the CompCam XE274HR and the specs are:

int. 274, ext. 280 deg. duration
At .050", 224/232 deg.
Lift .555" int., .565 exh.
Lobe Sep.: 112 deg.

Keep in mind the spring rates to avoid valve float. I'm planning on getting the K-kit so everything works together.

The XE274HR has been known to pass the sniffer with GOOD cats on a stroker motor.
I normally don't include it in my 'smogable' camshaft catagory....but it has been known to pass.

It is a VERY good camshaft! It will out-power the X303 on this combo.
