More at story link above.......There was one engine sitting in the Ford Performance PRI booth that almost went overlooked.
You wouldn’t know it from a standard Aluminator XS, that is, until you read the spec sheet in
front of the engine. The A52XS engine is derived from the M-6007-A52XS part number.
Partially GT350 and 2015 GT parts, the A52XS boasts power capabilities of over 570 horsepower
through its 317 cubic inches.
We took a 5.0-liter Coyote short-block – put the GT350 heads, cams, and intake on it
and picked up 100 horsepower – Mike DelahantyWe are working on some other ideas. Maybe we can get some more displacement out of
this engine with more stroke – Mike Delahanty, Ford PerformanceThis photo best illustrates exactly how well the GT350 cylinder heads paired with the Cobra Jet
intake manifold work on a standard 5.0 Coyote. The additional 15 cubic inches and half a point
of compression is what makes the additional 41 horsepower on the 5.2-liter.
