Stock LS2 long block with an LS9 cam, headers, cats, and a huge Magnaflow (with an internal x-pipe). Please excuse the whine from the "bad alternator bearing".
The deal was I got to modify the truck if it still drove like stock. The only complaint was how slow it made her Colorado feel - the words "maybe we should supercharge it too" followed. Running 11.9@116mph w/1.6 60' @ 5200lbs and being wife approved ain't too bad for the spare car.

Mike @5200 lbs that is a very impressive mph/e.t.

Thanks guys!
Le sigh.
The point wasn't a max effort build. I openly and intentionally left power on the table for a variety of reasons, including, but not limited to: emissions compliance, cost (just needed set of decent beehives to support), wife's happiness, ability to work with a tight converter (2600rpm Yank Truck Thruster - because towing), and above all else longevity and reliability (the short block has 219K kms on it).
I really wish people could grasp that sometimes less is more.

That combined with the extra lift of some rockers and I doubt I lose any torques. I'm pretty sure this won't buck or anything.
Nice job getting into the 11's with it!!!

This is good. That 220/230 spec I came up with in the OP was based on the ls9 cam. I put the EVO at 58 and used 230 degrees duration. Then I set the IVC at 45 and stretched the IVO until I got to -11 overlap.

Looking forward to the results on this.

Cost is the reason why we drive 450hp street cars and not 1500hp turbo street cars. Of course its a limiting factor. In my eyes its all about the performance per dollar. We arent winning any championships with 346ci NA LS1s, no matter how good the heads and cam is.

How many people chase SBE or cam only records? Quite a few. Quite a few shops have dedicated track cars just for that. So yes you can win with 346s etc.

Why are you taking it personal? If the ls9 cam changed price like the ls6 cam did in the upper 300s you think it would be as popular? Doubtful as you can get quite a few aftermarket cams that use ls6 springs for that price that perform better. The price is the main draw.
As it is quite a few are subscribed to the sloppy mechanic stuff, buy an ls9 cam then wonder why their gen3 engine wont start all the time or starts and acts funny then gets upset when they habe to spend at least $130 more just to get the ls2 front cover, another crank bolt, a 1x cam gear or a new double row timing set etc and either buy a $30+ cam extension harness or try to extend theirs. We have helped at least 8 guys in that same situation this year and I've seen even more. At that point they are pretty upset because they were told the ls9 cam was just as good as all the others but cheap so that's why they got it and you can use cheap ls6 springs. Adding double the work and double the price doesnt seem worth it to me because they only got half the story.
On this gen4 app yes the ls9 would work and if you looked i even mentioned OP Vader to use it with 1.8 rockers to gain the lift.

Ls9 cam is already a 3 bolt. Idk, I know some big timers used it in some of their more timid SC and NA builds. I was told lingenfelter was one of them. But its up to the OP. Id personally get a cam with more aggresive lobes and a tad more lift to pair with worked 799s or 243s. Probably a single pattern 220 or smaller. Single pattern for more midrange torque while taking the penalty at the top end, because street car so who cares.

Its a 3 bolt yes but it has no rear timing pickups. So you have to adapt a gen3 block to use it.
The big guys dont use the cam because it makes more power than an aftermarket cam. Its chosen because it makes power but its cheap. Its so whored out now any co that sells it with free shipping for 125 ish only makes pennies on it. After cc fees etc its barely worth it. And most will sell it (esp on ebay amazon etc) without telling anyone you cant use in gen3 without extra cost. Again in those situations we come in and get them the right parts, but still doing it once it alot better on the mind and wallet than 2 or 3 imo.
