Hopefully Woody will chime in on this - the head he and Burton Brown are developing REALLY sparked interest at PRI last winter, including with the engineers at Ford.
Woody, don't get mad at me but in the interest of correct citation, the cylinder head used on Burton's engine was designed, developed and patented by John Stowe. You and John have briefly discussed using CFD to model port configurations but don't know if anything came of it. John certainly knows there is value in your services but dollars are always in short supply.
The Stowe cylinder head has been around for quite some time in 1600 cc Ford BD trim but hasn't found a home in racing...yet. Power output improvement is significant over just about any other normally aspirated (NA) 2.0L out there. Burton's engine produces 342-347 hp depending on who's dyno you use. Fully developed, Stowe believes 375 reliable horse power very likely. Taking this one step further, Stowe thinks a Ford YB family of engines has potential for 400 hp given more optimal bore spacing, valve size and cam profile improvements. Cost to develop is the only thing holding John back. Anyone out there who would like a 400 hp, NA 2.0L for your race car? Give John a call.
I can't verify this but I think Burton is building a gen 2 version using an improved Stowe cylinder head and cams. Clearly, if this engine sees the light of day, records will likely fall.
