Ly6 cam suggestions Picked up a low mileage ly6 for my notch build. Looking for suggestions on a cam/springs. Leaning towards carb but have not ruled out injected yet. Deleting vvt. No plans to port the 823s as of yet. Possibly spray. Car is going to be ran to and at the strip.
You should look into one of the Sponsors on here to Spec a cam for your needs. 6.0 Carb Cam for Nitrous. I would say something around a 234/242, lift of .600-.630 and LSA 113-116 depending on Nitrous Shot. 3600-4200 Stall and BTR .660 Platinum Dual Springs with Titanium Retainers.
Do you have more Specs on the car since it will see a lot of strip use?
Will the engine use the stock bottom end and pistons?
Vehicle?
Vehicle Weight?
Intended Axle Ratio?
Transmission type?
Intended Tire Size?

Stock internals as of right now
93 notch body
Starting at full weight/interior and going from there
Not sure on ratio. 9 inch rear
Thinking 4l80e
275 60 15 rear
We have a 233/239 6xx/.6xx 112+2 that would work well for either carb or fuel inj.
There are a few lobes we can use for lift depening on if you are going for max effort or just a good street cam that performs well at the strip also.
Takes a 3200-3600 stall. would be ok with 3.55+ gears.
385 for cam or complete kit is 685 with dual springs and hd pushrods.

Can I ask why you are deleting VVT? I've been looking at some of the VVT cams that come with the profile data needed for the tune. I too have an LY6 and am looking for a cam. Have you thought about adding a LSA supercharger down the road. Thats what I want to do, so I want a mild cam for NA that will also support LSA down the road. Thinking possibly LS9 cam if I do a VVT delete, but VVT is normally a benefit.
Gms vvt is not really a benefit the way it works. plus having to lock out its range of motion hurts as well.
The ls9 cam is ok but seriously lacking in alot of areas. its cheap and its a 3 bolt cam...its only good points.

I know that HP tuners supports variable cam tuning. Texas Speed has a cam and they give you the tables that would get dropped into the tune programming. Don't be intimidated by the technology unless it is unreliable like DOD. (Not stock but at higher lift) VVT is like changing out your cam while driving. If you can get a better torque curve from it then why not keep it? I too am new to gms vvt, but vvt has been around in hondas and toyotas for a long time and is usually more desirable.
Vtec and ivtec and dohc and even sohc vvt is completely different from gm. The only relevant part of the gm system is it changes the icl of the cam basically. In doing so in the movement it does add...or subtract from overall duration of the lobe, but the cam has a fixed grind. The perf cams have to lock out most of the movement of the cam phaser. TSP gives you the tables to modify for the lockout but not the total tune for it. No company could do tha as every combo and application is different.
