You need a cam sprocket that has the x1 reluctor "tooth" like the pic... I don't know if the 3-hole sprocket fits the 1-hole cam, can probably be made to fit... this sprocket is what GM gave me when I asked for an LS1 cam sprocket... I assume the dowel hole is in the same position as the LS3 cam.
Also need the front timing cover that accepts a cam position sensor.
Also need a cam sensor extension harness to reach the timing cover.

The other thing is that the intake/exhaust splits on the LS3 cams won't be optimal for a LS1 car. The LS3 cams are made with the purpose of very high flowing LS3/L92 heads on the intake side, let alone the exhaust portion. It could be done but isn't worth the effort without adding LS3/L92 heads in my opinion. You'll make more power of course but with all that trouble you could just add a LS1 spec'd cam for better efficiency.

No! LS3 does not have VVT or DOD. 1X cam positioner has been deleted from the cam core as stated. Its a pretty lazy profile, better to choose something else even if you did trip over one in the street.

While big splits between the intake/exhaust durations haven't been common practice in recent years, newer technology has shown this isn't the case. Many assume such spec's are only geared towards nitrous cams, but manipulation of the valve events is more more indicative of the ENTIRE powerbands' performance than simply the advertised durations @ .050".
Hell, most of Geoff's (co-founder of Thunder Racing) EPS cams have 8-12 degree splits (even for stock-headed LS1's), and many are starting to notice why cams with small(er) intake lobes and generous duration splits are outperforming larger cams.
