[QUOTE="GT Premi, post: 14368189, member: 121775"] Anything the '13/'14 can handle, the '11/'12 can handle it, too. Put some knock sensors on the '07-'10 and it could probably handle more than any of them with that iron block. I haven't heard a single story of any of the aluminum blocks letting go, though, at any HP level. I've only seen that [i]one[/i] video that probably all GT500 owners have seen of an '09 letting go on the dyno. But I'm pretty sure that was just a crap tune. I still trust Carroll Shelby when he said these engines can comfortably handle 1,000HP [at the crank.] He didn't qualify that with "with some better rods and/or pistons." How much power does the Cobra Jet make? Now consider we're all running de-tuned Cobra Jet engines. If I'm not mistaken, the Cobra Jet can be had with up to 2,000HP. (I might very well be wrong there, and of course, now you're talking about some serious forged parts and fueling upgrades.) I honestly wouldn't be too worried about pushing my car out to 900HP at the crank with stock internals. Why 900HP, you ask? Because from what I've read, that's about the limit of efficient power out of the Whipple 2.9, anything beyond that and you're overworking the blower. I said all that to say, don't sweat 700WHP - 750WHP on stock internals. Just get a good tune, strong fuel pump(s), and big injectors. [/QUOTE]
