I understand... I took my 95 Transport and actually Modded the thing... Had the engine flowing better due to the Lower intake porting and the 1.8 Roller Rockers... Rebuilt a trans from a Supercharged 3800... The 1-2 shift at WOT was nuts... Was fun to drive for a van, a few people were shocked that it could move.. And even more shocked when they found out I got better mileage than they did in their car...LMAO
My Average was 24 Mixed.. Would easily do 27-28 On the Hwy, But I have a Lead foot...
The Transports with the 3800 were rated for 26 Hwy, But I have heard 28-29 seemed to be the norm.. Its a surprise to see a van that can pull down those numbers isn't it
