Ford Motor Company and Roush have teamed up and are developing/testing a 7-liter V8 engine. This motor will utilize an individual runner manifold, and twin injectors per cylinder will feed Hemi-style heads. The 7-liter will sport 4.250 bores and a 3.75 stroke. (Note: Ford's old 427 was 4.23 x 3.78 / the 428 was 4.13 x 3.98) which should give it a high-winding nature.) This new 7-liter reportly has enough room/ beef to grow to 7.5. The placement of the cam is uncertain at this time, but word is it's a cam-in-block pushrod motor. Roush currently has it punching out 800 HP using E85 fuel. Ford is very tight lipped about this motor only stating a "full media presentation will go down in due time". The motor's expected future use is Ford's truck line to special Mustangs.
