Just my experience, my first LS conversion was a 6.0, I went with a carb, intake, MSD 6010-EFI scared me, lol
I had a string of Procharged cars, and had a built CSU blowthru carb-the setup was easy, easy to tune, and ran bullet proof. My next build, another 6.0, LS3 heads, intake, 90MM TB, Procharger, Holley HP setup-what a fn nightmare, I bought into the plug and play, spent months try to do it myself, finally got someone to remote into my laptop to help me.
Now I got braver, another 6.0, Holley 4150 intake, 90 MM adapter, 90 MM TB, turbo, Holley HP-much better this time, I actually used the tune from my first FI experiment, then tweaked it for what the engine wants-I love the datalog feature, and a lot of the other features that kill the engine if boost or something else gets out of whack.
But, a lot depends on what you have on the engine-they all need fuel pumps, so that's a wash-stock ECU, harness could be one of the cheapest for EFI, then Megasquirt, then Maybe the Holley HP $1500-1600)
I scored a GM 4 bar intake for $95, $250 for a good used 750 Holley, and the MSD is like $350? so for under $700 I could have one running-If you scored a comp harness and ECU for say $200, added in someone to rem Vats, etc, modded the harness yourself, prob the cheapest
After all that, I think my carbed/Procharged setup ran the best, just a diff feel than FI, lol

I have done both with the LS1 in my boat (currently EFI with Super Vic EFI and AccuFab. I need to pull the engine this winter to freshen it up, I will put it back with a carb.

No ****? OP - are you planning on keeping that stock cam? Seems like you're leaving a lot on the table with what SEEMS like a mis-matched combo?

Asking this question is like going to a Yankees vs Redsox playoff game and asking which is the better team to random people in the stands. Gonna get a bunch of this answer, a bunch of that answer, and a bunch of F you! answers. Just like here on tech.

Nice choice!

With this cam and the bump in compression with the 6.0 243 heads what should i be do n roughly in hp?

I have never done or seen a direct comparison to a LQ9 camshaft, but I would think around 75 horsepower or so. It will be dramatic for sure.

How hard is that hot street cam on valve springs?

I assume stock LS2 springs won't cut it. You recommend 600 lift behives springs as an option but don't seem to sell those? Are you suggesting something like Pac 1218's ?

Also which of your pushrod options would you recommend with that cam, 0.080 or 0.120 ? Is a certain length a pretty sure bet or better to measure before ordering?

If it ain't broke....

CAMMOTION PERF

This camshaft is designed with very smooth and stable lobes. With this camshaft you can use our .650" or .660" dual valve springs or our PAC 1218 beehive performance replacement valve springs: http://store.cammotion.com/single-beehive-valve-spring

The .080" pushrods are perfect for this application: http://store.cammotion.com/516-x-740...-wall-pushrods

How would that cam work if boost were added in a blow thru setup

What are the details of the setup?

I guess I'm going backwards! I'm going carb on my setup, should be much easier to tune on my end. Now if I was a stock or small cam guy I would have stayed FI but I like to try different things and race my car and tuning it was just a pain for me. Luckly I had Jeramy Fomato tune my car but after doing an LS6 intake, a Fast 92 then a Fast 102 trying cams, heads, trying etc it got to be too much for my lil brain to comprehend.
Cheaper to go FI? I guess for some good street cruisers maybe but all out, cost is about the same. FI results was 10 sec car NA that I could drive anywhere, I'm looking for a 9 sec car NA now but carbed.
