Thinking of using this Cam Hi Guys,
I am thinking of using this cam in my LSX 454,
The cam I have in currently is:
247/254 .700 .700 110 on a 1.8 ratio
The new cam I am thinking about using is:
247/251 .666 .666 113 +3 on a 1.8 ratio, I don't know what the +3 means.
The engine has approx 11.5:1 comp.
What are your thoughts on using this cam?

It was all designed and built by my mechanic in Aust, but the final figures weren't what I was hoping or expecting, so am looking at the cam above to see if I can get more out of the LSX 454.

OK so that is what the +3 is all about, as for the rockers, they are the standard LSX rockers on the LSX heads. Do you think there would be an issue with that?

I'm with Oakley, sounds like you'd want a bigger stick. At least in the duration figures. You need to PM Patrick G and get a professional recommendation...

I haven't got access to a scanner at the moment, so can't post the power curve.
Some more information on the engine is:
LSX 454.
Fast intake with 60lb injectors
Heads shaved and ported by higgind race heads.
Compression approx 11.7 - 11.8:1
1 7/8" headers 3" dual exhaust.
This is what I am going to use the cam in.

Ok here is a new cam in the mix, it doesn't use the LSL lobes, it is using HUC instead. Designed by the person people said to go too.
It is:
251/263 .670 .670 112+3
This cam sound more like the one I should be using, a little bigger in all respects, but should have better low rev manners than the one that is in it, I am now waiting for his recommended grinder to come back to me with a time frame to get it done.
Thanks for suggesting Patrick G, appreciate the help.

BTW did he reccomend you use EPS lobes? Just curious as my next cam I want pat g to spec out on CamMotion, Ed Curtis at Flowtech, or EPS to grind my cam on their proprietary lobes everyone raves about now a days. When my car had the current cam it has put in it TR cams were all the rage. Shows how long my car has been cam'd!
TR cams are still very good proven cams that use their own lobe design. Basically anyone that uses their own lobe design for the LS motor is really shining when it comes to results over a more traditional SBC lobe which I dont know if that is what was used previously on your first cam.
You will be pleased I am sure.
