Hello Hey You,

i’ve selling my 1987 B250 windows Van, was with 318 last year carbureted engine. I made the conversion to E85 with a new carb and timing advance + 4 degrees. It was really good to drive sincerely better than with regular gas.
so, I going to buy an other one Van . Find one from 1989 with 360 EFI engine. I don’t buy the shop manual at this time.
