Sorry to hear that. Great times and great pwr & tq though! I really wouldn't have expected a stock block/internals to live with that kind of power anyway though. Question- I scanned the thread and I don't think I saw what your A/F was or timing was? Also IAT? I'm just curious. I don't think your motor would have lived long with that much power regardless. Good luck w/ your new set up!

Stock rods are plenty strong, rod bolts leave a bit to be desired, but damage to them comes from excessive rpm mainly, not power. Most people don't realize that hypereutectic pistons are really strong, probably similar in strength to a forged piston of identical design. Thy don't have as much crown as a forged piston does though and that plays a large role in strength as well. Forged pistons can take a lot more abuse than a hyper because they are not brittle like a hyper piston is. That leaves more margine for error in the tuning.
My friend has a stock motor with a t76 on it, he is going to push it until it pops, I'm tuning it. We are thinking we can get away with 17psi on a regular basis with good gas. Gotta adress the pegged maf issue though.

Ok... well i dont want to read through the entire thread... nbut have you torn into the motor yet to find out what is wrong?
I mean, you would get a #7 missfire if you burst a headgasket because the water flowing into the cylinder (you said you smelt it) would put out the spark. That would give you the misfire. same for liftin a head.
Anyone want to chime in and tell me if im wrong or write?

i almost garauntee it is a head gasket. propable cause is a combination of too small injector and last one in line for fuel.
btw - do a search for mike browns tt ce. he went 9.7-9.9 and never pulled a valve cover. it was an incon tt kit with meth. he put down over 700 rwhp and never had a problem with it.

Soon as I get back from FT Lauderdale. I am now in a debate if I want to put her back together and still try to get her in the 10's on a stock block. I think I have been beat to more powerful STS Setups.... but I would still like to be the first capable of it on a stock block. Then I want to be the first in the 9's When is the first LS1Tech race for the season John?

that and the fact that it would draw water into the cylinder causing it to try and hydro lock slightly. on that note, you may of caused a slight fracture on a rod, just something to keep in mind. would suck though, I would like to see 10's out of it.
