440 V8 375 hp @ 4600 rpm, 480lb-ft @ 3200 rpm.
440+6 V8 390 hp @ 4700 rpm, 490 lb-ft @ 3200 rpm.

The four barrel 440 in a Road Runner story is myth that's existed since... well probably since the cars were new. I'm confident in saying the only way a 440 four barrel ended up in a 68-70 Road Runner is a dealer build (excluding the Superbird, or course.) I've heard the 440 Road Runner story a thousand times. Every time I've been taken to see one of these cars, it's ended up as a 383 with a 440 swap, or a Six Barrel car with a single four intake swapped in place of the three two's.

I suppose it's possible one was built. No physical reason it couldn't have been. But I live awfully close to Missouri, and so far nobody has ever shown me. If someone ever does find one, I suspect it will be parked right next to a 71 LS6 Chevelle.
