Anyone with Ford "BOSS" 6.2L experience?
I'm looking for direct involvement with engine building and or tuning of the 6.2L V8 that is used in Ford Raptor's and F250/350 trucks.

That would be Don Bowles.

Wow, no on on this site has played with one of the new 6.2L engines? They were delivered in Raptor's and F250/350 Super Duty trucks.

Truck durability means the 6.2 features an iron-block with large coolant passages and dual knock sensors. Ford allows a 2mm overbore to the stock 102mm cylinder bores, giving 386 ci with the stock crankshaft.Built for Speed
Curiously for a truck engine, the first 6.2s seen in public were in racing applications. The first was the mysterious drag-race engine spotted in Don Bowles' yellow S197 in NMRA competition. A Ford/Roush collaborative effort, the mystery engine (with apologies to Chevy's Mark III 427 Mystery Engine of early 60s Daytona fame) kept the Ford world buzzing with rumors in 2007, as neither Ford, Roush, nor Don would give a word of explanation about it.
Don posted a 9.10/145 best with the unnamed, naturally aspirated engine in the 3,300-pound Mustang, which immediately tells you the combination was hitting in the 800hp range. What we now know is the beautifully detailed Bowles engine was a hand-built 6.2 prototype punched to an even 7 liters, or 427 ci. This was done by making a core change at the casting plant to get an extra 3 mm or so of bore diameter in the one-off iron-block, then over-boring the cylinders by the "organic" 2 mm allowed for field servicing. The resulting approximately 5mm-larger (0.194-inch) bore gave Don's engine about a 4.217-inch bore-call it a 4.250-inch bore among friends. If necessary, lengthening the stroke a bare 2 mm to 3.82 inch would have given the magic 427-inch displacement with a 4.217-inch bore.
Likewise, Don's cylinder heads were developed finding their limits. First they ported a set of stock castings as necessary, then cut those heads apart to see where they were thin. Some form of rapid prototyping fabrication was then employed to make special heads with the necessary extra metal. These castings were ported further. The eight-throttle, individual-runner intake on Don's engine was obviously a one-off and allowed excellent top-end breathing for the max-effort drag sprints. Ford insiders say burning E85 fuel, this combination was tuned to between 750 and 800 hp.
