Anybody using this cam? How does it go in a 347?

 

[347]

I cant answer your question, but I have looked at the specs.

Its a bit of a girly cam.......why not go for something like a comp cams

XE282HR(2600-6500)

232/[email protected]
.565/.574 LIFT
112LOBES

I agree, the X303 is a bit of a baby, what is that comp cams cam worth?

Its a bit of a girly cam.......

Girly is a bit harsh. You FF guys are a tough crowd...

I already have some Comp valvetrain parts and I am a fan of their cams. The XE282HR is a fair bit wilder than the X303 (+8* @ 50th), so perhaps the XE274HR is the go? The car is a daily driver and cannot be too wild on the drivability / noise / economy / emissions front.

Agreed, I recently changed from an E303 to an F303.
Abit lumpier in the idle, Alot more go when starting to rev out.
Good drivabillity & economy, so far,,,...

i got a xe270hr early jan and it cost bout $540

 

[347]

I had a look at the xe274hr..........all I can says is at least you have taken off your skirt !

 

[Fresh1965]

Cam im looking at at the moment is as such:
Trick Flow track heat roller cam: TFS-51402002
236/248 .574/.595 lift with 110 deg lobe sep

 

[347]

What is the rpm range?

 

[Racer]

I replaced my 282 with a 274 because i wanted a smoother more streetable ride.

Not that there is anything wrong with the 282, its a strong cam, but i'm getting older and less tolerant....

Yeah the TFS cams are really popular in the US at the moment with the TFS-51402000 being used on the 5L engines and the TFS-51402001 and TFS-51402002 getting good numbers with the strokers. Plus they are nice and cheap.

TFS-51402001

224 intake/232 exhaust .542"/.563" 112 with power range of 2800-6300rpm

TFS-51402002

236 intake/248 exhaust .574"/.595" 110 with power range of 3500-7000rpm

 

[Racer]

The XE274HR is pretty much TFS stage 2 equivalent, and the XE282HR is TFS stage 3

 

[347]

Why dont you guys use solid rollers?
Is it a cost issue?
Or is it that a solid roller wouldn't give you much more power than a hyd roller?

 

[MrLandau]

The Comp cams XE282HR is listed as having a power band of 2600-6600 in a 5.0. The stroker will bring that down a couple of hundred revs. The peak lifts are .565" inlet & .574" exhaust.
The stage 3 Trickflow is 3500-7000rpm and .574" inlet & .595" on the exhaust.
Both cams would well suit the Trickflow/AFR heads where the heads are still flowing well into the .600" lift regions - but the stage 3 would probably be best set up advanced to bring the power range down into realism.

Racer, you have this bumpstick so can you please give us a few of your engine specs?

If a 347, at what RPM did peak power occur? I don't want to rev the crap out of my engine for a few extra ponies. My current cam (Crane 2030) peaks at 5500 and I just want to extend this to 6000/6200 but no more.
