I have been looking in purchasing a 30 year old Van, it has small block V8 305 (5.0 L) 4 bbl carb., 4 speed AT transmission. It would be used for about 9,000 miles per year in environment where 1 litre of petrol costs €1.44 or ~ $7 per gallon. Is that crazy or what? - Does the transmission have TC lockup or how can I check this? - What cheap modifications would boost MPG (electric grill fan, flat underbody)? - What MPG would Wayne get out of this thing and what techniques to use? FAS is not an option.
