What are the engineering differences between the 260 and the 290?
The Compression Ratio is the biggest indicator that the internals will be slightly different - even if it's only the pistons themselves. Of all the bits they list for the Boss 290 at www.fpv.com.au,
can we assume that many of these bits are also bolted into the Boss 260?
The REAL question though, is how many people might consider slotting in a Boss 290 Cam after the warranty expires (as long as the ECU can feed the extra fuel) to make up some of the gap between 260 and 290kW ?
