I'm sure your car would run terrific with a 2500 stall in it too. People have run that cam in stock shortblock cars and it never peaked within the pcm's limits, so you're right, comps recommendations aren't far off at all.

 

ok i found that the cam needs minimum 120# at 1.75... so looks like the LS6 springs with 90# wont be enough.. the 986 springs they recommend are at 132# 1.75...

so what are the 918 springs at closed height? looks like these are probably what i need

 

Why would I run a 2500rpm stall? I wouldn't run a 2500 stall on a stock cam. I would run a 3600-4k stall on a stock motor, but that is just me. I happen to have a stock shortblock and my car peaks before the pcm limit. Maybe i'm the only one. Well, actually my friend Chris has the same cam, but his is on a 113 (mine is the older 114), and he runs the stock pcm as well. We are the only 2 though that have this cam, that also make peak power before 7k.

 

if you set up the ls6 springs correctly, you'll be at 115/310, with a much lighter valve side than the recommended dual springs.

 

Got a link to the dyno graph?

 

It would be safe insurance to run 918's to ensure there is no float and so a simple miss shift doesn't grenade his motor.

 

the lobes are mild, he'll be fine. Plus he already has the springs.

 

Nailed what? You ran 115mph before stripping that thing and putting a single plane on it. I don't get where you have any credibility whatsoever regarding how your setup works.
I think it's because you are a cheerleader.

 

It had the single plane on it back in '07, lol. It also had a fried stock opti with a worn out center bearing. The car was bucking hard and breaking up above 6k, which we traced to the opti becoming unstable. The MSD opti cured that and then some. When we took the stock opti apart it was full of little pieces of bearing debris. The car was light then too. It's maybe 100lbs lighter right now, if that. You know nothing about my setup other than what i've posted. It's faster than your big cube solid roller, and one of the fastest stock shortblock cars around.

Says the guy with the man crush warning, lol.

 

Well however you want to spin it, that's up to you. The fact of the matter is your power to weight ratio plays more of a part than a setup that was put together without a whole lot of smarts. Got that dynograph handy?

It doesn't take away from the fact that you are one of the biggest cheerleaders on this forum. I mean it's a smart strategy and all for a solid barg at least...

 

Yep, just a hodgepodge of parts and a random hack attempt when I show up at the track. No idea what the tire pressure is, how much timing the motor likes and how fast it's brought in, what temp the motor runs best at, what rpm it likes to launch at, what camber the front tires are set at, what settings the shocks are at, how the valve springs are adjusted, what oil the motor runs best with, what oil level it responds to, what temp the plugs are, or any of that pertenant stuff. Plus a whole lot of other little tidbits that I have no idea.

I just put gas in it and push the pedal down when the light goes green.

No dynograph, sorry. It's just tuned with a wideband.


Not sure where you get that from but it doesn't offend me in the least. I have no problem giving credit where credit is due. I can respect people that have done well with the LT1 platform and/or other things. Maybe it just pisses you off that you are stuck in your little rut in VA and you are jealous that other people get to do the things that you can't? Misery loves company.

 

i agree.. dont really want to chance it on this engine. I can use the LS6 springs in my 5.3 engine in my 00 Yukon.. it needs a head gasket change.

 

... and the hundreds of pounds you've taken out?
Again, you can mix it however you want, but from your setup I just don't see how you can get on a soap box and say just how great your setup is. I don't get it...
LOL the pontification you come up with is hilarious. By all means, if cheerleading makes you happy then knock yourself out. I mean everyone looking for any credibility needs those just like you. May you wave your pom poms high and proud.

 

umm.. ok guys.. you're both totally off topic here..

just ordered the comp 918's .. found a place for $150 plus free 787 retainers.. (i already have those so i'll return the ones i have..) yay me

 

You're right. Sorry about that. I think you're far better off taking advice from those who don't run a tin can and try to sell it off as something to be reckoned.
Just a thought.

 

cool let us all know how it turns out.

 

I think the LS6 springs would have been fine set up at the correct installed height, BUT I also believe you made the wise choice in upgrading to some #918's and saving the LS6's for your 5.3. Your peace of mind is worth at least a good portion of that $150 (minus your returned retainers).
