Really what I'm going off more than anything is you said your brother did a stage 1 and didn't like it wished he had gone bigger, that would be a 2 or a 3 for him. You have more motor and you're considering doing a 2..
You also said you plan on doing a converter, that pushes your cam size selection that'll work well, into larger territory.
the summit truck cams are even smaller than the cam i listed when looking at them.
how much larger would you go?
Even talking to the pro's that sell them, it is not like they are even suggesting similar cams, they are literally all over the place. the one I listed was suggested by Roger at Vinci.
the stage 2 and 3 and 4 truck cams are larger then the one you posted
But I cannot make a suggestion because I would run a 4.56 gear with that 4l80e around a 3500+ stall and something in the 228/235 to 230/237 range with a set of 243 heads

yeah, i don't want the stock converter to limit me.

too much gear for me and stall for my application for sure. turning some big highway RPMs with a setup like that.
You have been a ton of Help on this. might bump up what i am wanting. I don't mind a good enabler when it comes to more power
Pretty sure i have seen that article before, Engine masters did a video on it as well too.
I'll up the ante and see what cams i find in a slightly larger range than i have been looking with a bit more lift and duration.
Well I hope in the end when it's all done seen as good advice (aka you're happy with it), it's hard to advise people on cams, stall converters etc because people themselves have such a huge range in what they find tolerable or what they like.
Have you called cam motion? If not, maybe call with all this info in your head and tell them what you want and what you want to avoid.
I have some experience but no where to the tune of those guys so I always think it's a great idea to at least run it by them or any shop that cuts and tests cams.
What Pooter said... Cam Motion, or whoever you call, will give you straight advice. They won't sell you too much cam, as they all cost the same, so they will make sure you get the RIGHT one. Just be straight up with what you tell them (don't guild the lily...) and they will spec the right cam for you.
Cam Motion and TSP seem to be more in tune with the LS engine's needs cam-wise. Maybe others too, but these two seem to get the attention around here, and there must be a reason.
The rpm range on the same cam on varying cid will vary also.
I may have said this before but our high lift asa made 440/420 on an ls1. on a 6.0 370 id expect nearly the same and more tq maybe but also a lower peak hp rpm. I try to be as realistic as possible when talking with customers about what to expect.
In a "heavy" car esp wagon etc you can make up for any bottom end losses with gears but mid range is all cam really. Make crappy tq there youll be missing out on ALOT.
Most advertise such unrealistic power bands you can even fully measure them so its just a guess. This cam is cut narrow to help the low end. Any cam closer with a wider lsa will need more rpm but miss out likely on peak tq also.
Our high lift hot cam is a nice option also and makes 400 on an ls1 with 243 heads and is likely exactly what youd want since its kinda hard to follow the post direction really.
Lift has nothing to do with your direction of thought though and .600 isnt huge by any means.
If you look at the 4 texas speed stage 2 truck cams and and stage 3 you will see what lift really does. if you are building a 370 dont cheap out on cam and springs.
Attached is the graph of all 4. the stage 2 clearly wins in the tq portion and stage 3 in peak hp but both high lifts make more torque and use a mich and higher quality spring.
600 lift is not huge, never said it was, but the duration is higher than any other cams suggested by anyone else. Hence why i said more cam than i would need with the greater duration.
I also never implied i was cheaping out on cam and springs. Said multiple times i plan on doing it once and doing it right so it will be the right cam, and matching springs and upgraded push rods as well. Not looking for the cheapest, just looking for the right setup.
But midrange and low end is for sure what i want my power to focus. That graph of the TSP cams is helpful for sure.
Most likely, i'll toss a dart at a cam list and run with it since there are so many options, and all will most likely work and i won't know what will work best until i get it running and driving.
Thanks for all the input. Now that i have the car, hope to really get moving. on it all since i was orignially hoping to get the motor almost done before picking up a car, but when a deals comes across you have to jump on it.

It would be my privilege to talk to you about the perfect camshaft selection for your project. Feel free to give us a call to discuss it. Ask for Steven 225-926-6110.

Thank for the help today Steven! I'll be in touch shortly to place the order!
Have you decided on a cam? BTW Cam Motion will treat you right, as you now know after talking with Steven.
Yupp, Heard nothing but good things about Cam Motion.
Steven suggested a custom spec cam yesterday, Similar to the ones i had it narrowed down to above. Plan on ordering next week sometime to get the ball rolling on this. With everyone here's help i got in the ballpark for the numbers i thought i should be looking at and it was pretty close to what Steven suggested.
