I pulled a cam out of a used ls1 i bought and was wondering if anybody could tell me something about it . I tried searching the numbers but no help , I believe its a custom cam
the numbers that are stamped are 2870 A , and a stand alone F
then there are numbers that are etched and they are
V9348
3714/3715 HR 115+3
If someone could point me in the right direction it would be appreciated

 

3714 Lobe (Intake) = Xtreme RPM High Lift (Comp Cams)

Specs are:

.006 .050 .200 Lobe Lift 1.7 Valve Lift
275 222 140 .332 .564


3715 Lobe (Exhaust) = Xtreme RPM High Lift (Comp Cams)

Specs are:

.006 .050 .200 Lobe Lift 1.7 Valve Lift
277 224 142 .334 .568

The Xtreme RPM High Lift are otherwise known as "XE" lobes. The cam has a 115 LSA with 3 degrees of advance ground in (112 ICL).

I'm think the other number is just a S/N, but I'm not 100% sure.

 

So is that like Nitrous cam, or turbo something around that ball park?

When you start getting up in the higher lsa in aftermarket cams yes your are looking at fi (turbo,sc) application, or just a smoother idle almost stock form. Usually the FI cams are in the 116 117 LSA for higher rpm range.
