[QUOTE="tt335ci03cobra, post: 16272296, member: 68944"] [USER=195665]@CD07GT500[/USER] nice build. Congrats and I want and hope you get tons of fun and miles out of that combo. Enjoy your car man, you specked a nice combo to make 1200whp at 6500 with for your gt500 and enough wtq to make a lot of diesels jealous. It’s likely prefect for Texas or the heartland. Im in the Rocky Mountains and also ended up at 1200whp but from 6500-8500 with a revvy 5.3 and 9.3/1 compression. All modular stuff. A key consideration of my build is that I drive canyons in the Rocky Mountains on 91 octane, and having more than 500wtq at 2500-4500rpm mid corner in a 3350lbs sn95 is ass puckering in a canyon. I like to pull out of corners 1/2 to 3/4 throttle at 6500rpm+ As my torque bleeds off. It’s very fun when I get it just right and surprisingly planted. The forward g force pushes the car out, and the relatively low torque isn’t overpowering my lasagna noodle (albeit built) sn95. Mine peaks at 700wtq around 5500-6000rpmon pump gas with 815whp from ~6250 to 8000 and only loses a little to 8500. My 5.4 experiences pissed me off after spending good money on great parts only to have them fail like stock parts. At moderate power levels. My current gt/gt500 heads are pissing me off too. So far I’ve pulled the heads 3 times and currently need to do a 4th pull in 7500 miles. This time it sounds like a rocker... smh So far in 7500 miles, my full tilt gt/gt500 mod heads have eaten: •ford racing reluctor wheel •ford racing tensioners •ford racing chains •ford racing guides •a cam lobe on a $500 stage 3 cam •3 titanium retainers •MMR billet chain •MMR billet guide heavily worn/replaced •2 stainless exhaust valves •one piston had to be recoated. None of it has been major failures but it’s been enough that I’m tired of modular head architecture and the incessant failures every 2500 or so miles of high winding use. Coyote’s don’t get these kinds of failures and that’s why going forward, I’m doing coyote based projects. Coyotes are also dirt cheap. F150 mills with trans can be had for $2500.
