OP, you'll love that cam. We finally got some great weather here tonight and of course i did a nice onramp hit. Cam just pulls awesome. I literally just did the cam kit from ws6store, stock pushrods, I don't remember if I did a timing chain or just threw the stock one on. i know i threw the stock 80k mile water pump back on lol.
A good converter is what my car is missing, but she pulls strong, a converter would just top it off.
Great cam if you ask me. Love my car on nice cool nights like these.

I wouldn't worry about bottom end torque much if you have good converter. Once you get over 2500 rpms, the LS1 starts accelerating quite nicely. I wouldn't go lower than a 3000 stall though.
Most LS1 torque curves I've seen are fairly flat in the 2000-3000 rpm range. You usually get a little bump around 3500, and have a peak close to 5000. That's why a lot of people recommend the 3600-4000 stall converters. I think that's a bit high for a daily driver. That's why I went with the Circle-D 3000-3200 stall converter. It's very tame on the streets, but does ok at the track.
If you still have the 4L60e, then 400 Whp should be a reasonable goal with the Hot cam. My cam is slightly bigger, and my car put down 382hp/368tq at the wheels. I have the 4L80e, so that robs more hp. You should get a little more Whp with the 4L60e.

Hot cam loses nothing anywhere. No torque or hp loss at any rpm. All it does is gain.
If you put it in and were disappointed than your expectations are way to high to begin with lol.
As far as torque, I need to be doing around 70 to 75 on the highway and turning around 2500rpm to get good acceleration by lightly giving it gas. I do think this cam doesn't get along with the stock lock up settings in the trans with my 3.73s. Never fails around 40mph is when I get power coming on and want to hit it because I'm around 2200rpm, right when I do it ******* locks up the converter, rpms drop to 1500 or so and it falls on its face at 45mph. Its more the sound change that i hate, the car keeps pulling but not like it would if i was at higher rpms and unlocked. 2000 vs 3000 is a difference in these cars. This is probably a trans/converter/ tune issue and i hate it. Setting lock up to 55 may help?

Why would you recommend the cam motion titan 2? Driveability? Valvetrain stability? it makes 10 more hp over some other basic cam? do you just like it?
I have the ws6store hot cam and Ive been toying with changing to a summit ls cam or something else, but then I realize I would probably be better off switching to true duals from my y pipe exhaust. Like I said, just curious why you say that titan 2 cam.

1. Intake durations for 5.7-6.0 f bodys and c5,6s below 220* are small and while the Titan 2 is only 4* larger that makes a bigger difference going from 218-222* VS 228-232* .
2. Exhaust durations for cathedrals in a NA daily driver up to ~ 6800 RPM should be between 0-+8* depending on the E/I relationship & the exhaust system, imo, obviously LTs , X pipe & True Duals VS Y Pipe W/ 3" or stock. (LSAs between 111*+2*-115*+3* determined by driver & Cam Guru of choice based on goals).
If I put a cam in my M6 C6 LS2 daily driver I will go 223*/227* 115*+3* (already have a LLSR in the C5) and want smooth driving, especially for when I have to drive in hilly SF with a manual.
I am also over 50, so a teen to 20s might want the 112*+3* as an example with the increased overlap & attention.
The Titan 2 has +4* intake duration and a +4* exhaust split (VS +9*) for the high-lift hot cam which is better suited to a stock or compromised exhaust or FI.
You are definitely better served by going true dual VS changing your cam for what you want.

Why is the 9 degree exhaust duration split bad for my combo? Is this too much for my tsp cnc stg.1 ported 225cc intake runner 243 heads with stock valves and milled to 62cc?

depending on the E/I ratio of the heads and the efficiency of the complete exhaust system. That's my opinion I'm sure many would disagree.
The hot cam is from earlier days in LS, maybe even designed for the OE exhaust system, adding more lift while certainly improving
HP & Torque everywhere does not change the overlap and manners during part throttle and cruise. Again not a "bad" cam just better options
if starting from no cam.

Just to clarify, the ws6 store HLHC is not just a gm hot cam with more lift, they smoothed some things out and updated the "tech".
I'm sure if I bought the cam motion titan 2 I'd be praising it too lol

Maybe the ws6 store tech guy can elaborate more about the big intake exhaust duration split vs a smaller I e split. I like that this cam has a lot of low end torque, and has a good lope to it, plus good feedback from people who are using it.

Here are the flow bench numbers for the tsp cnc stg.1 ls6 heads with stock valves that I have. Intake cfm Exhaust cfm lift. .200 147 114 .300 207 148 .400 255 187 .500 292 202 .600 313 220

Every extra * of exhaust duration NOT needed is lost torque and throttle response, helpful at high 6500+ RPM with 230* and larger Intake durations.
Not with a 218* Intake and an efficient exhaust system, about 5* to much imo.

All SINGLE patterns, look at the data and graphs on their site. 220/220 & 224/224 are both better imo than hlhc.
your ported heads will add 25-30 more. I would have them do 220/224 or 224/228 if you want a split on lsa of your choice
112 or 114, 112 will chop more, but a great tune and 650 RPM IDLE will max the chop/lope of ANY cam

Ws6 store tech guy says that the ws6 high lift hot cam will make more average torque and have much better bottom end power and torque than the tsp 223 226 and eps 222 226. I just want to put the right cam in the first time that is well matched with my heads, gear, 1 3/4 lt headers, tsp 3in ory, ls6 intake, and circle d 278mm 3000-3200 converter. Car is mainly a street car or weekend warrior with occasional runs at the track.

Regarding intake durations 220* and less = small, 221-229* = medium,
230*+ = large for a 5.7, imo. Many here on Tech will say my brackets are too Conservative.
Talk with tsp they will know better, ....they built your heads.

I think you are over thinking it. One won't make your car run 12.2 and the other 12.7 and another 11.9....all the cams are going to perform similarly. I picked the HLHC because I like the idle clips I heard and I knew I could still daily drive the car. Plus for me my old lt1 I threw a massive cam in it with stupid high lift and was getting killed by lt4 hot cam cars. So always wishing I did a basic hot cam...thats what i was looking for. During research I learned the gm ls1 hotcam was old tech and found ws6store recently upgraded it to be competitive. Once seeing dyno numbers i went with it because its a game of 10hp after that.
Like stated tsp has a cam that will gain 30hp, and one that can gain 40hp. I assumed 10hp wasn't worth the possible tuning issues since I was going to use mail order tune. I chose to leave the 10hp on the table knowing there's other ways to get that 10hp back that don't effect driveability. Dyno tunes are $6-800 here.
Don't over think it. All these small/baby cams will work for you and none of them will set any world records. Listen to idle clips and pull the trigger.

I gotcha. I just dont want to feel like I put the wrong cam in my engine that isn't matched with my combo of parts. Maybe I am over thinking it. Just want to do it right the first time I guess lol.
