I own a 1989 Chevy G30 Cube van. The motor is a 5.7 350 TBI with 24,000 km's (original) on the dial.

I am averaging about 27 liters per 100 km or 11MPG

What would be some of the "best" modifications to make to a vehicle such as this? I am very mechanically inclined and would like to know everything that may save fuel right down to spark plug gapping.....

The truck has a 14' box and tire pressure is at 58PSI on all six tires. Curb weight is about 3600KG's

Is there anyone else on here with cube vans and if so, what are you averaging per 100/km or MPG's?

There are no current modifications to this truck, everything is bone stock. No air dams etc.
