What is the hp and et record for stock longblock 07-10 gt500's? I saw where evoperformance went 8s with a stock longblock. The et question was out of curiosity. But the hp question wasnt. I am trying to figure out a good hp stopping point for my car. I have an 08 gt500 motor with about 15k miles with a single turbo setup. I have gotten mixed opinions. Some have said 600rwhp and I have seen some make 850 or more, one of those made 849rwhp on 91 octane. I will be running a th400 so I know my rwhp numbers will be different than a 6spd. But im wondering if i can go to 700-800 or what? All opinions would be appreciated.
Record hp and et stock longblock?

Complicated subject as there are so many variables as to your supporting mods and conditions. As for 849 on 91 oct. highly doubt it.
I made 801 rwhp with 21psi and a 75 shot back to back when my XCal2 failed and would not flash the nitrous tune to my car. We thought my tune had been uploaded to the car but Jon Lund was remote tuning my car at the time and flipped out when we made 2 pulls with full timing on the spray. LOL!
If the car was turbo charged I could see it might make that power for a short time if you didnt rev it hard.

My car went 9.778 at 144.32 mph on a stock long block, kenne bell 3.6lc supercharger, auto trans and 80 pound injectors. Exact hp I was producing is unknown, but i believe i was over 800 rwhp on that one pass. Stock engine is still tickin' courtesy of a jon lund tune, c16 race gas and changing out the spark plugs each time i tracked the car.
That is a true statement from my understanding. I still wonder though whether that 8 second turbo car still has a functioning stock engine. I highly suspect not
But you were not on 91 octane. :uh oh:
lol - that is true 
What do you think the automatic cut off your ET.
how about 9.69@147 on 100% stock long block, tremec tr6060, 4.0 whipple,no nitrous, no cams or porting, 821rwhp on a MUSTANG DYNO using 94 octane + torco

I know of an 03 cobra that has been some 8.80's-8.90's on stock longblock
Revs will kill these motors faster than a certain power number. Keep the revs down and you'll be safer.

And what would you guys say a safe rev limit is? I am REALLY REALLY wanting to be able to go 8s with this motor setup before I have to build it. This is in a 3700lbs race weight car with a th400 setup. Hypothetically saying that the whole car works the way it should. Im thinking it will take somewhere between 700-800rwhp through the th400 to go 8s. Again, if the car is dialed in.

3700 race weight
Is that 3700 pounds with driver, or is that just the weight of the car? If that is with driver, that is pretty good. I was shifting between 6,000 to 6,200 rpms due to fear that the rods wouldn't handle 6500 rpm plus.
I would think it would take more power than 700-800 RWHP in order to break into the 8's, unless you are going to pull some amazing 60 foot times and rev higher than 6200 rpms. My car weighed 3,924 pounds with driver when I ran my 9.778 pass. This was with a 1.508 60 foot, and suspension was still not dialed in. If my 60 foot could be taken to a 1.30, I likely would have been in the 9.4's. That is a long way still to a high 8 second pass.
With dialed in suspension, extensive weight reduction (and transfer) to the car, I think an 8 second pass would be possible. But, is it worth the risk of having the rods fail?

800rwhp through an auto is quite a bit of power, but you should be able to do that on a stock long block. How long it will last is hard to say. Turbos will be a safer way to go than with a big blower, though.
I would think 800rwhp with a dialed in setup and a brake will go 8's or very close, but I'm no expert. I would probably spend a little extra money and swap out the rods/pistons for aftermarket units.

3700 with me in it. It is in a 2000 gt. And I will be shooting for high 1.2 low 1.3 60's. A friends tt cobra went 9.1 full weight with around 700rwhp through a th400 so that was kinda where I was getting my et vs. power ratio from.
