Add $800 for cams/springs/retainers. So far around $2500. Get a competent engine builder to assemble the heads and degree the cams, get someone to tune it. Around 300rwhp, which is around what a supercharged NPI engine will make (not a PI intake/cammed NPI), with the flexibility to grow further via supercharging, nitrous, whatever your liking. Add the fact that a 300rwhp N/A car is going to be one hell of a lot more fun to drive all around compared to a centrifugal charged 300rwhp car just due to the torque curve being so much wider, it'd be the better daily driver setup. I wasn't saying a N/A engine will compete with a supercharged car in their optimal form, I was just saying the ported heads, cams, and the newer PI setup in general will be really close to a supercharged NPI car, with the added benefit of a newer engine and the capability to have a LOT more more power than an NPI car could puke out. Plus he has a daily driver, if he wants to go bigger in the future, he'll have his old block sitting to the side so he could slowly save up and build a forged bottom end, and have something he could switch out pretty quickly with only a weekend's downtime instead of shipping stuff off to get machined and assembled. It's win/win.</p></blockquote><p></p>
