I'm in the midst of a total rebuild on my engine and I need a new cam. Previously I had a tsp torquer v3 and loved it but the high lift mixed with hard use killed one of my valve springs. I've been hearing about a xfi/xer cam lobe combo. Is there any special set of springs that I would need? As far as power goes, what size cam would I need to put it on equal footing as the v3? Thanks in advance.

Bump for help from the cam gurus.

 

Not a Cam Guru..But im going that route via T3 or T2...What Springs did you use last time??..On what Heads?

 

Patriot duals on stock ls1 heads.

 

Well the only similar power your gonna get is with a custom grind cam..I would stick with what works (T2 T3), and for sure use Comp Cams Beehive with that setup..I heard Patriot duals are kinda stiff, so if your revving very high, failure is unavoidable..Hope that helps

 

I'm not afraid of using a custom cam. That's the point of making this thread.

 

Oh ..Then Stick with Comp Cams Beehive..Cant go wrong.Patriots are a little stiff/Brittle, thats what i heard/read in other posts
