Blew my motor. (pic) Now which direction to head. Ok heres the pic, running a 150 dry shot on cam and bolt on car with stock fuel system.
Now was talking with the guy thats going to do the fix and he wants to do a 6.0 liter block with a forged stroker crank, forged double diamond pistons, forged Eagle connecting rods, 232/236 .595/.601 112 LSA, Absolute Speed Stage 2 heads running about 11 to 1 compression making a 408 stroker. Now some have said the cam is too small for that big of a motor, is that true? Also how much power would this setup put down on a 2002 car with an M6?

I also believe the cam is too small for that motor.
But that is for what I am trying to do with the car.
I see you run nitrous and that makes me believe you race the car.
Tell us what your goals are for the car and let us know how much daily driving you do.
If you have the correct bolton's you should defentially be high 400's.
If you go bigger cam I would also say do stage 3 heads for the best setup.

You need a bigger fuel system to support a dry shot that large. You ran lean and detonated = broken piston. The better your fuel system, the safer and more you can run.
You don't need a forged crank. The stock crank is good to at least 700 RWHP.
Just get the APE Cheap Street Forged block for $2799 + core, upgrade your fuel system, convert to a DP kit, pull some timing, etc, voila.

Gotta agree with cannibal....get with APE and get an iron "Cheap Street" short block....cannot beat the pricing or customer service.
If you are going with a 408, get a much bigger cam and a stage 3 head port. Should make some nice power, even without the gas.

Just because he blew the piston the way he did dosen't always mean he was way lean.
I had this same problem with a very similar hole in the piston and was running 11.8-12.1 AF through the whole band.
I did have about 70 boddles through the car and all being a 150 -200 shot. Sometimes the pistons just give up.
Also I didn't say anything myself about the nitrous because it looks like you might be taking the Juice off the car. No where in your question does it say you are going to have nitrous and if you are then this would change peoples oponion's of the cam you should consider. Most go with a 114LSA when running N20.
Anyways I would defentially say go with AP as I here no negatives about them and all positives. PM Chris or Brian and they will take care of you.

Well now after talking wit hthe guy somemore it will probably be a 433 stroker instead of the 408, 433 is the biggest the block will allow. I am kind of strapping myself cash wise to get this done so I am stuck with my stage 2 heads for right now. I will probably put a small shot back on it but at this point I am hoping it will hardly ever be needed as I am hoping to be in the high 400s at the wheels. The car is going to be a daily driver so I am trying to keep it halfway streetable, the guy building said this cam was kind of small but would still make good power and be streetable. If everyone here thinks that this setup, 433 stroker and heads and cam on a 6.0 liter block, will make close to 500 rwhp then thats what I am looking for.
Later on when I pay off some debt, about a year I guess, I will be getting a turbo system for it. I am hoping to be close to 700 rwhp with this motor and about 10 psi.
