300bhp/ton said:that is a very inaccurate statement.
the ls1 is 5.7 liters with 345bhp so
345/5.7 = 60.5bhp per liter
The current 4.6 has 300bhp so
300/4.6 = 65.2bhp per liter
So infact the current 3v 4.6 mod engine is mnore efficent in specific outputs terms. An you can huff and puff all you like but these are FACTS.
I was talking about mileage efficiency
Yes, the 4.6 puts out slightly more HP per liter, but the LS1 still puts out much more power overall than the 4.6, and gets better mileage doing it.
What's really pathetic is the 4.0 V6 in the Mustang. 210 horsepower and hardly any better mileage than the 4.6 V8. I rented a brand new 2005 V6 a while back with 550 miles on the clock. Did a couple hundred mostly highway miles on it and it got <20 MPG.
