Looking for cam recommendations
Looking for cam recommendations So currently I’m running a SDPC LS6 power max plus cam in my LS swapped 79 Monte, stock LS1 with ls6 intake, 4l60e with FTI 3000 converter. Winter upgrades include Fast 92mm intake with Nick Williams 92mm throttle body, 36lb injectors,Livernois CNC ported 799 heads and 3.42 gears. Car is a cruiser/ street car only no track use, looking to maximize my future planned upgrades. Should I upgrade the cam to something else or run what I have ? I know it’s a loaded question but if I’m gonna change the cam, lifters and springs I want to do it now. Any suggestions ? Shooting for 400+ to the wheels and decent drivability is this setup feasible ?

That cam didn't come alive until almost 4000 RPM, so if you don't want to rev to 7k it probably makes sense to go a little smaller. Something like 228/228 @ 110+4 would have about the same overlap (same driveability) and 4 degrees earlier intake valve closing, which should make the power come on earlier.
Sorry, currently Holley cast manifolds but I am looking for a set of long tubes that will fit without having to dent them up. No cats 2.5’’ dual exhaust with x pipe and Borla mufflers.
Also running terminator x max if that matters.

For reference I made 400rwhp with a LS1/t56, un ported 243 heads, Fast 92mm intake, 1 7/8 mid length headers with a 224/230 .581/.591 112lsa cam. On another LS1/4l60e build I made 435rwhp with a fast 92mm intake, ported 243 heads, 1 7/8 LT headers with a 228/232 112lsa .625 lift cam.
I would stay a little conservative with cam choice because a 79 monte is a heavy car, you want some low end torque to keep the car fun to drive on the street.

If you were to change, i would suggest flowtech Induction's streetsweeper HT. 228/232, .612, .600, 111+3. It's a monster torque cam with power pretty much everywhere.
Tell you what, I'll take your cam, and you try the new BTR LS1/LS2 Stage 2 V2 cam:
221/241, .624/.636, 112LSA. Brian says it'll drive like a stocker. It has a little more overlap than I want (7º) which is why I'm still leaning towards the Power Max+ cam (-3º overlap). I want something quiet for my build: LS1 with 862 heads with the bigger valves, LS6 intake, PnP stock TB, going in a volvo 240 wagon. I think ever 350rwhp through my 4L60 would be great!
I was also debating on the SUM-8715 "ghost cam" (which I think is the same as their stage 1 turbo cam): 222/233, .600/.575, 115 +3 (-2.5º overlap). It seems much more than low 220's on intake duration on a 5.7L gives too much usable power down low away in exchange for gains way up high - not ideal for a DD street car IMO.

From what I have seen of the ghost cam before and after dynos, it maintains torque down low and then gains up high. The 8720 on the other hand should gain everywhere vs stock and out torque the 8715 but have a little less hp at the top. 8720 is a great improvement vs ls6 IMO and better than a 220/222.
