Power Curves and Overdrive |
By allan - 10/20/2003 11:42:19 AM; IP 130.76.96.19 |
I read and article somewhere about overdrive not always helping with gas milage if the engine power curve does not fall in the RPM range that the engine is operating in when in overdrive. Can someone shed some light on this and does anyone know where a stock 390 engine (rated at 300HP) starts developing its power? This is in a 65 Tbird with Cruise-O-Matic and a 3.00 rearend. |
