What could have been

Not exactly about the LT-5 but Ford showing where things could have gone. 600hp from a 5L motor NA.

Fine technical article. Love the individual TBs.

Interesting design to drive the camshafts. One small chain connecting the two camshafts together and then a separate drive chain. Allows for the camshaft phasers.

LT5 design for comparison.

Interesting how the chain tensioning is flipped 180* side to side.

The Audi 4.0 TFSI is a little monster too. Been around for a while, but has BMW and Merc. scrambling (circa 2013)

"Although the 4.0 TFSI makes massive peak torque early at 1,750 rpm and carries it all the way to 5,500 rpm, it’s a diminutive thing. It’s just less than 19 inches long.

The power output of the engine is astounding. What gets me exceptionally excited about it, though, is its cylinder-deactivation technology that reduces its fuel consumption – on average – by five percent."

Ford seems to be "on it" w/ their new flat plane motor. Tons of new stuff coming down the pike. But, one recent article I glimpsed alluded to yet another pushrod motor being considered for Chevrolet's mid-engine Vette. (Just can't get away from those pickup motors...??).

I'm with ya Dom. You've got your ear to the automotive track; what do you hear coming from GM? More pushrod pickup motors for the mid-engine Vette as a recent article has suggested?

I guess designers found it important to have the chain tension applied in the same manner on both banks. or to have the chain introduced to, and taken away from the driven sprockets in the same manner on both banks.
Thsoe 2 large chains are very well supported.
