I know this should be better suited in the tech section, and is is over there, but I'm not getting input help me out guys.

I have a 1982 Regal that I am swapping a LY6 into. It has come time in my build where I need to choose a cam. This is my first build so I am not going pretend I know it all, so I am reaching out to my fellow ls1tech'ers,..ies,..oids...(whatever) for some opinions or personal experience.

This be the plan:
1982 Regal
'08 Ly6, stock dished valve relief pistons, vvt removed, (10k motor so I don't have plans to do anything internally
L92 heads stock, I will mill as much as I can safely to bump compression would like to see at least 10:5
LS3 intake, 90mm TB
LT headers, no cats, dual exhaust
4l60e 3200-3600 stall
3.23-3.42 in the back

These be the goals:
100% daily driver
good mpg's
good drive ability
easy life for the valve train
at least 420rwhp/400rwtq

Ok so moving on to the point:
I have narrowed it down to an Eps cam for sure. I have it narrowed down to
a) 222/230 .600 ish lift on a 114 lsa or
b) 226/234 .600 ish lift on a 113 lsa

I actually already put in the order for cam (a), but Geoff gave me a couple days to change my mind.

I know either cam will meet most of my goals. (a) will be a blast around town and perform in the range that i will use the car on a daily basis, but will it let me down at the track when I get that urge to Go Fast! and well (b) i know is going to give more mid to high range, but at what cost to my daily fun.

help me out tech.

Maybe the conversions/hybrids section. I know several g-body builds there. Good luck man.

Go with cam b. My brother just finished up an l92 headed 6.0 with that cam. Car made 466/440 on pat g's dyno with killer low end torque numbers.

That sounds like a sick build? I wonder what other mods he did? Do you recall at what rpm that torque came alive?

I want to say it made ~380rwtq at 3000rpm but it may have been 3500, cant remember. Other mods are just the normal stuff, custom ram air, under drive pulley, 1-3/4 long tubes/ magnaflow cb and a built drivetrain w/ m6.

He plans on making a build thread soon, I'll be sure and point it out to you when he does.

my cam came in today :) Although it came in as 226/234 113(+2) vs (+3)?? I will call Geoff on Monday, maybe i goofed on that detail.
Any input for my limited knowledge on the difference in cam characteristics that will make?
Either way I need to quit bs'ing and get a new timing set and headgaskets coming to me. And start recruiting some help with degreeing, and checking PtoV.
