What year efi?

What year did the efi have a mass air meter or where they all speed density?

I think only Cali trucks were mass airflow. Early 90s I maybe wrong

I think Mass. had them one year also. 1996 IIRC.

Down in FL the trucks were Speed Density. 96-7 460 were SD

Mustang went Mass Air in 89.

Come to think of it, I don't think I have ever seen a OEM mass Air 460.

I think this is been going over before, seems like I remember Randy Malik giving insight about it. Personally I've only seen one mass airflow 7.5L truck, a '97 F350. And it was out of California and made its way here to MI in salt hell. When I popped the hood and start looking at things I was little confused at first, not ever running this combination before. Kind of like finding a unicorn, except a 10mpg crew cab sorta horse.

Thanks guys now he can see this... it's not locked away in some unforseen place.
