[QUOTE="Dave_6, post: 10450404, member: 66590"] It has the article on the JPC head porting for the Coyote. The test car had only Kooks LT's, 3" x-pipe, Magnaflow catback, JLT and a tune. With those mods and on JPC's load-bearing dyno, it made 424 rwhp and 412 lb-ft. After the porting it put down 446 rwhp and 422 lb-ft. Peak power with the stock heads was roughly at 6400 rpm and the ported heads are making 40+ more rwhp at 7400. Torque picked up ALL the way thru the powerband as did the horsepower; it never once dips below stock. :rockon: [/QUOTE]
