By the way kiddies, don't try this at home...
To have a modular handle 8000 rpm it takes more than any of the head 'kits' from any of the vendors on here. No matter stage 1, 2, 3, 4, 100, etc, etc - all of the head packages for sale use the stock tappets/followers, the same manley exhaust valves, and one of the 1 or 2 standard spring choices and they are nowhere in the realm of being 'built' for high rpm spinning.
If you want to safely take your car into the 7400+ rpm range, you have got to get the right exhaust valves, a custom spring made for your set-up, and most importantly - you need to have JESEL in your car...period. Yep - expensive as sin, but Jesel is the only thing you want moving in your train. I have been through more motors than most and I think the train is the weakest link on 99% of the builds you read about on the internet.
If it doesn't look like this, it's not Jesel...

It is A LOT more horsepower than that...lol You have to understand - on a roller dyno, once we get around 800, it blows the tires off the rollers and we get out of it. Look at the dyno chart - it is at 800 at only 6300 rpm and the line is going straight up like a mountain. It will keep pulling and building power through 8000 rpm. I am going to be shifting at 7400 rpm.
I think it is at about 1100 rwhp right now if the dyno could hold it.
I believe in this very conservative tune up (only 10º of timing and 10.4 a/f) it is easily going to see mid 8's it's first time out at around 170 mph and I'll slowly turn her up. And I will be DRIVING her to the track...lol
By spring, I'm hoping to see a 7.9x @ 180 mph...
