So bang for the buck, what is the best OEM cam still available to reach the magic 400HP+ mark on an otherwise stock LS1? I see several cams were available, LS9 or even the illusive ZR1 cam?
Is there a chart with PN and cam specs available? Especially one with expected outputs with specific injectors.
Also I see the Yellow Flex Fuel Injectors have a greater output rating, anyone running these?

I think I found my cam, the "LS9 CAM" for those still looking:
Anyone know if the "Yellow" LS6 valve springs will mate well with this cam?

I don't think you'll reach 400 rwhp with that cam on a LS1.

So... then
The short list to install an LS9 Cam in a 2000 LS1, (Or any early truck LS engine), with GM parts bin parts.
LS9 CAM has fewer bolt holes (Not a 3 hole cam) so appropriate bolts etc.?
Anything else? Before the power adder?

- Cam-LS9--GM PN # 12638427
- Valve Springs for 560 lift PN #
- (Rocker arms 1.8 ratio LS9 Optional) PN#
- LS2 front cover with sensor PN#
- Harness extension for front cover LS2- PN#
- LS2 Cam Chain, PN#

I wouldn't run 1.8 rockers with this cam, the intake opening ramp has as much intensity as a Comp XE-R lobe. I know a guy who broke a Comp 918 spring in 1500 miles with this cam using stock rockers. Bear in mind this cam was designed for a head with titanium intake valves, not solid stem steel valves.

It doesn't have a cam position reluctor on the back, so if you want to use it in a LS1 you'll need the front cover with the cam position sensor and the harness extension. We have the front cover for $89 http://www.briantooleyracing.com/ls2...-12633906.html
I don't think you'll reach 400 rwhp with that cam on a LS1.

Thanks for the info, does that timing cover come with the crank sensor attached,... nothing else to buy? (Except the harness extension).
Also is the Crank Trigger harness extension a GM part as well?

1- Forget about I want 400 hp mark with OEM cams in LS1.
2- Establish where you wish to make power in the rpm range, (where will you use it), based on the answer to that search for a cm that fits that rpm range.

I am not stuck to the 400hp, I'm more after the torque numbers as this is for "Short course Auto-x Good Guys style", but did I not see a Powernation/Engine program with a junk yard 4.8 and LS2 heads with a 566 intake, 576 Exh cam reaching "394hp 274Tq EFI" or "377hp with a 650CFM" carb?.
