not too old but not too new.
right now I have a 92 ford F-250 with a 460 as a tow rig and I love it. The truck is huge and I need to put pillows on the seat and my pedal extensions but going up a hill with a trailer and a dart on the trailer is no problem.
Kinda weird tho....the 460 gets the same gas mileage with or without a load ....kinda weird.
