[QUOTE="MSimpson, post: 178304, member: 2620"] I recently had my motor rebuilt with some head and intake work; it dynoed at 621 hp 600 torque with a 850 double pumper. I currently have a mass flow but am looking at fast or Big stuff 3. I read that Tims new rig is pulling 700 hp with mods. GM Performance claims 620 hp / 590 torque. So my question is will the fuel injection and the 180 degree headers create 80 more horsepower, because I'm right there before these mods and that might be my answer, or were there others mods, and what did the dyno say torque ended up at. Thanks any help would be appreciated. [/QUOTE]
