Nice torque Trackspeed! That's got to be a beast on the track.
For guys with streetcars who don't necessarily need the track-abuse durability of a fully built engine on ethanol, would your setup on a stock VVT longblock and 93 octane pump gas map produce a similar dyno graph, all other components being the same (same intercooler, exhaust, appropriately sized injectors for pump gas, etc)?

Looks great Andrew! I now get the earlier 6258 recommendation. Will 99 head alter the curve drastically?
