Mild cam for LS1?
Thanks for that info, I wasn't aware that TSP actually manufactures their own cams, I knew they used to be Comp based. I wonder how their lobes compare. I've not seen their newer stuff used down here in Australia (seen heaps of their earlier Comp manufactured stuff though).
I have listened to your Hot Cam, just for anyone that is curious, while its always hard to tell in videos, just comparing it to my Cam Motion cam, mine seems much more mild. Different car to mine and different aim for the cams though I would imagine.

I've noticed that its suggested that the reason a lot of the "truck cams" have lower lift is due to using factory or factor style springs, personally I don't see the point in that, wouldn't you be better off changing the springs to something better and reaping the benefits of higher lift? Or is just common that buyers of these types of cams want to use factory springs?
We don't have "Truck Cams" here but that type of cam seems much more popular in Australia than the USA but I think that's in part because our cars like Monaro's (Pontiac GTO) and Commodores are heavier than the Camaros and Corvettes so low down is important. A lot of the US grind cams seem to focus on a higher power band, which I should have paid more attention to.

My tuner said he could have set the tune for a bit more stealth if I wanted but that it was set up where the cam worked best. It sits well with me so all good but you do know its cammed. I read stealth as meaning undetectable. It seems to me that is around -14* which is actually the overlap of the most radical factory cam fitted to an LS1 in Australia (the Callaway supplied C4B). That could be adjusted lower with tuning though I would imagine.

Should be smooth & stealthy while providing excellent performance
with Stock,ported, or Aftermarket Heads, along with room to
grow.
My mild cam has -8.7 overlap and has a very noticeable lope, which is fine by me, but would not meet the OP's requirements. You probably want less than -10 overlap.

I would go 114* +3* if I We're to use that cam, for myself, but the OPs initial unfounded fear of these specs would cause me to err on the side of a more conservative/Wider LSA.

My approach must be backwards. I do not really care about LSA. I specify the four valve events I want. LSA just ends up being whatever it is.
That GT2 cam is like a slightly larger ls6 cam. About 118.5
Tuning does make a big difference for better or for worse.

Like i said even if you work backwards you still end up at lsa. Without lsa you cant grind a cam whether its calculated at the beginning or the end. Its what determines overlap. Without lsa you wouldn't know. Youd have 2 durations.

The late ls6 cam has a smaller base circle. The stock ls6 valves have a +.100 installed height so to use the stock prs and have correct geometry with the stock rockers etc, they had the smaller base circle. Supposedly about .050 but could be a little more. Or mayb its backward and the ls6 valves were made longer to match the cam.
Either way the 01 ls6 didnt make the power. Blame it on a tune maybe, but it had all the same components.
Either way, neither are available new, and some have been passed around more than a blunt at a bob marley concert. So that choice is on the end user. Plenty better cams out there that are new.

The Bob Marley reference......ALL TRUE
The stock LS6 valves DO NOT have a higher installed height
The 01 used standard weight/length valves for the .525" lift cam
The 02-04 engines got the .551"/.547" lift cam and GM put the hollow stem valves which are .0236" longer to create proper lifter pre-load with the reduced base circle cam
The 01 C5Zs had pup cats off the manifolds (4 total) whereas the 02-04 only had the two larger ones down below.
Also the air box opening (hole) was made about three times larger for the 02-04 year Vettes
So perhaps the tunes were different; however the cam/air box/& the 2 less cats all contributed to the 20 horsepower rating difference

By stock sound I meant the cam had no noticeable lope. I was not commenting on the exhaust itself.
I start with the valve events first, calculate duration, overlap, and LSA off the events. i'm just saying I don't start off with a notion of how the LSA will behave and then bump duration up and down to compensate
That's all I meant by my approach being backwards.
