[QUOTE="_Lariat, post: 16080584, member: 193599"] It doesnt matter per say, but in the grand scheme of things. I'm not planning on revving my pickup that will be towing things to 7k rpm all the time to use the most power potential that 4v heads offer. I could argue that same logic with the old school 4v Cleveland heads myself, as they were, and still are lackluster under 3500 rpm. Another thing to look at is cost, lifetime, and simplicity. 4v heads are nothing to sneer at, but in a fleet situation, less things to fail, the better off. Longevity, while I havent heard of any issues with the coyote platform, it makes power at a higher rpm. Back to the fleet, I dont want my drivers revving my trucks all the time to tow a load from A to B. Cost. You ever rebuilt a set of 4v heads from top to bottom? It ain't cheap. 32 valves to grind and lap, as opposed to 16. This is in a v8 application. Someone with a little more knowledge on port designs, and the likes may be able to put a little more insite on the situation too. I know the duramax, 24v Cummins, 6.0, 6.4, & 6.7 powerstrokes will be brought up, but they're turbocharged diesels that run like crap without any boost. (I work on em, I've experienced it, it's an interesting drive back to the shop when CAC tubing fails, or blows off. Lol) Dont get me wrong my inner power chasing freak would love to see the 4v 5.7 coyote, but really, it's not in fords interest. If they were going to do it, the 6.2, or 3.5 ecoboost would never have existed. Sent from my SM-G955U using the [URL=http://r.tapatalk.com/byo?rid=92568]svtperformance.com mobile app[/URL] [/QUOTE]
