[QUOTE="Ben99GT, post: 9344852, member: 3519"] I'd say it will respond to basic mods comparably. The new Tri-Ys aren't too much better than the old FRPP 2V headers, which were worth pretty much jack on the 2V over stock logs. The Ford guys were saying the new headers are worth 6 HP (at the flywheel) over 3V logs, so maybe 5 rwhp. The new Coyote intake port outflows the Ford GT intake port by 4%, and outflows Yates D3s up to .475" lift (D3s flow about 355 at .475"). This isn't mild stuff. Then there's 11:1 and TiVCT. Don't underestimate the advantages and possibilities of TiVCT. If we were to believe those insider slips that these engines were making ~475 HP on the engine dyno during testing, I expect serious potential improvements from a tune. Perhaps the kind of tune gains we haven't seen before, when the tuners finally get comfortable with all of those VCT tables. Then there's the intake manifold, we're told that they are so great, yet the Boss 302R Coyote already has a MUCH different intake manifold. To me that is a major clue. I expect these engines with a full array of bolt-ons and a tune to perform far better than we have come to expect from the typical C-head builds, even most big bore/strokers. [/QUOTE]
