Curious what this set up will net me and if there’s anything else I should do with the car or change anything around before tuning gets done and while the car is took apart, thanks in advance
stock bottom ls2 m6
g6x3 cam
Tfs 220 64cc
.045 cometic
11.4:1
fic 445cc
walbro 255lph
btr .660
fast 102 port match
1 3/4 lt’s
3” spin tech
Monster lt1-s
If you already have 1 3/4”headers, your money would be better spent on a 4.10s gears
to help with drivability with that big cam
that said 2” headers would add 12 rwhp
I think that Gov’t Mule make a song about these cars
its call endless parade

gears was next on the list for sure, the song is the truth lol
The stock LS2 injectors & fuel system will go near 600rw & very tuner friendly. No need to change any of that.
4:10's are the best mod & bang for buck there is .......being the drive line is out to change the clutch. I did not have a positive experience with that clutch, it had to come out. I'm running a balanced Mcleod dual disc, very driver friendly.
I went from 1 3/4 LG's to 2.0"ARH, besides improved power there is a low rpm dip in the torque curve the bigger header minimizes for whatever reason. I'm still looking for some additional power, I think the knock sensors are over aggressive with the LS2 E38, struggled with that when my LS2 was near stock. I'm planning to head back to the dyno this season & see if I can sneak a bit more timing in.
Your cam choice will have some low speed driveability crankyness. I have made 3 cam changes, I'm very close to perfect manners now. Power has stayed the same with major under curve improvements.

What cam did you settle on? I too went through quite a few cams before finding the one that is perfect for me. I got an expensive education along the way.
Nice setup. When all said / done be curious to see results. SAE, guess is you'll be around 510 - 525 WHP range.

Thanks alot!
I’ve read and read and read until my head hurts picking parts and seen this to be a proven hci combo for a lot of people, fwiw it’s going on a dyno jet and will be tuned by race proven performance in Kentucky
I’m curious to see how these 220’s stack up to the 225’s
if I break 500’s or get in the 480-490 range I’ll be more than tickled
Don’t have buyer remorse( IF) your a first time buyer buy 2” headers
so if you ever decide to move up to power adders ,you will have it covered
here the difference between 1 7/8 headers and a stock msd 7 intake
and 2” headers and the same intake ported by Greg Good,i didn’t have torque loss
I'm running the 220 "fast as cast" on my LS2 take 25 1000's off the heads, if not you won't be happy, I ended up pulling the heads again to do just that, and boy did that wake it up! I used a .044 cometic, so your quench is good!

glad to see somebody else using them!
what was your cc before you milled them?
pat g told me at 64cc with a .045 gasket would put me at 11.4:1 compression ratio, I was worried about ptv clearance if I took anymore off the heads with the cam size but idk lol
I don't know what CC, don't care. I put the heads on and lost 25 HP, ended up pulling the heads and milling them 25 thou, I figure I have about a 11.5-1 CR now, back to the dyno and I'm putting 498 RWHP and 488 RWTQ, I'm running a Comp Cam for Cathedral ports,
Got it tuned yesterday at race proven performance in Harrodsburg, ky and couldn’t be any more happier, said I could get higher numbers if we let it cool off some but I’m not chasing numbers

Wow, you didn't lose anything at all.
I think the difference between 1 3/4 to 1 7/8 would be more pronounced that 1 7/8 to 2" but still, you're right-plus you picked up a good amount up high.
