It is stroked 5.4 liter 4 valve heads and an intercooled supercharger. Price not published yet. I'd expect $54K base. I'm going to buy a powerball ticket right now. Chuck
The increase in displacement is not due to increase in stroke but an increase in bore. The increase in bore is due to the use of a plasma spray coating instead of the use of steel sleeves. I believe this process was first used in the 2011 or 12 aluminium GT500 5.4 block.
It would be beyond cool (and logical) to have a high reving, normally aspirated Boss 351 (5.8) to replace the current Boss 302 as a special edition car to slot between the GT and GT500. Hell maybe they could install the FRPP twin 65mm CJ throttle body on it and call it a Cobra Jet engine. Yes Ford you can send my check for this brilliant idea in the mail, but cash is preferred.
