Question on heads and cam.
I can get 398 ft-lbs and 389 hp out of my otherwise stock denali truck with stock z06 heads and cam. What i'm thinking now, is going with a better cam and stock ls1 heads, since the major hp comes from the drop in 72cc chambers to 64cc. Ls1's are a little lower on compression and will be safer on my truck. My question is now, will a comp cams ls6 spring and pushrod upgrade be enough for a bigger cam to work with the stock ls1 heads? Say I buy a used set of fully assembled heads and end up getting a used comp cams cam with say approx 224/224 and then upgrade with a comp cams spring upgrade kit, will this be OK and reliable on my truck? I can do this cheaper than stock ls6 components as ls1 heads are like $100 versus 450-600 for ls6 and a used comp cams cam is only about $100 more than a used ls6.
LS1 Heads $100
Cam $200
Spring upgrade kit $160
total cost is $460
Sell my truck stuff for $300
net $160
HP gain 50 over stock. does this look too good to be true?

I have how to build high-performance chevy ls1/ls6 v-8's the book. They picked up 50 crank hp with stock ls6 heads and cam on my truck. I would only need to pick up 62 crank hp to equal 50 rwhp. But I was talking crank HP anyway. Their's was without a tune. I'm wondering if LAPD can dyno tune an AWD truck?

power programmers pick up about 25-30 rwhp on these trucks since the stock tune sucks so bad to begin with. I had planned on this setup a vr-6 king cobra intake, dyno tune possibly later, and this setup.
Goal is about 425 crank hp.

also they tested to 5800 rpm, which is where hp peaked with the ls6 setup, since this is the stock redline. I'm hoping with the upgraded valvetrain that I can go up to 6500 or so. I believe the rotating assemblies are similar to the ls2's, but just come in an iron block. Anyone know if this is true?

stock I only have 337 hp, and 375 torque. These are crank numbers, not whp.
I called comp cams and know what I need now. I should be able to get 450 crank hp with the new setup. 6500 redline
Not bad for a AWD 6000 lb truck. ALL FOR UNDER $1000
I wish I could get 113 hp out of my z06 for $1000
