[QUOTE="Beyer, post: 62983, member: 344"] First off, I know very little about 'building' an engine. I got a good deal a few years back on my 5.7 Vortec (low mileage). My motor runs pretty good now, but could always use more. I keep getting mixed opinions on building a 5.7L Vortec. Some say it is hard to get it to run correctly with mods, others say no big deal. Anyone have any experience with these motors beyond stock? Currently it has stock internals, headers, 2.5" exhaust, K&N, computer reflash that was supposed to be good for about 25 HP (Ed Wright/Fast Chips here in Tulsa). So I am guessing the current HP at 275-300??? What could I get with a cam? Roller Rockers? Are heads a waste of time on a motor with Vortec heads (I hear they flow really well already)? Fast Chips said they would reflash the computer after my mods for $150. How reasonable and reliable would 350 HP be? 400? I keep debating on doing this or going to a 6.0L. I estimate it will cost me roughly $3,500-$4,000 to swap in a 6.0L and could get about 375 HP from Intake, exhaust, and computer reflash. On the other hand my chassis is already set-up for this motor (motor mounts and fire wall), computer, wiring harness, flywheel, torque converter, York compressor, and some spare parts. What do you guys think? [/QUOTE]
