Hi so I just purchased a 05 twin turbo gto with a 408 stroker, long story short I drove it for the first time ever and crank decided to break, so tore the engine down from what everyone is telling ne block is no good, score a rod and piston broke oil pump pretty much whole bottom end is toasted it was all forged internals. Now I'm trying to find a built forged internal shortblock to put my 0821 heads and my camshaft in, however I do not know if the camshaft is even good for a turbo setup because I cannot identify it. Any help appreciated!
Looks to me like a super aggressive turbo cam although there are more lobes that dwarf those, probably for bigger inch setups
No surprise to me that "crank decided to break"... after all, there's no such thing as "too much cam", only, "not enough motor"... sounds like you mighta got caught up in that
You planning on running in the TV show where the Memphis crew goes wherever to run the 405s, NOLA, the Aussies, and so on? Looks kinda like THAT kind of a build

So I called Comp cams and wrote down the specs he read off to me listed below, also I'm looking at buying a stock 6.0 lq4/9 and just sending it with a good tune for now maybe aim for the 700 whp mark. I'm just wondering what cam I should buy to put in, I also plan on reusing my 0821 heads unless I shouldn't?
So is this "stock 6.0 lq4/9" gonna have some massive turbos and so forth? And you're gonna trust to "hope" (the most famous business plan of all time) that you're gonna somehow escape "crank decided to break"?
That is NOT a suitable cam for anything REMOTELY CLOSE TO "stock". And of course, anything REMOTELY CLOSE TO "stock" isn't gonna come anywhere close to "700 whp".
Come back when you have the motor you want to pick a cam for, and we'll help you out. Meanwhile, sell that thing to one of the TV show "Street Outlaws" kinda guys.
Be a bit more specific in your goals. Maybe even a bit realistic even if it hurts.
Those were the cam specs of the 408 stroker that the crank broke in, it supposedly was making 1000 whp and 873 whtq on 16lbs of boost, never got to get it to the dyno because first time i took it out the crank broke. Reason I wanted to ID the cam was too see if it was actually a good cam for a turbo and if it was usable for a stock build. Which brings me to my question about what cam should I be putting in a stock lq9 6.0 that will be sufficient for twin 69/73 vs racing turbos.
Why does everyone claim a stock 6.0 crank is good for 1000 crank hp?
They have been ran at 1k hp in many builds. The unknown here is HOW LONG can I run it at 1k hp? Might last 100 passesmight last 3 passes. Having said that, Ive seen a $4500 Winburg break in half in a circle track application. We made a door stop out of it. Anything can break. Nothing is bulletproof. And with that camshaft, Id imagine your engine had the life rung out of it every time it ran. Ive got that exact cam sitting on a shelf in my shop except mine is ground on a 112 LSA.
That's what I'm saying lol. Either spend 6-8k getting a built shortblock, or buy a 1200 buck 120k mile 6.0 and send it with a good tune? Could do that 6 times over and the 7k shortblock might last just as long as 1 of those it seems.
