Engine Compatability `

I would guess that you would need to install all of the sensors & actuators from the '89, as the EFI systems would not be compatible between the two. I'm not sure what year the trucks went from speed density to mass air, but it was probably around that time (86, 87?)

Both trucks used MAP and not MAF sensors. It should be a pretty straightforward swap. Bob

Please don't quote me:

But as I inquire for information on my project, the bellhousing patterns are all the same for the 302/351.

I have to keep checking, I want to build what's unique, not what everyone can go out and buy!

which 351 ??

Huh.. I could have sworn my old '89 F150 I6 was mass airflow. Maybe not. Cars cut over to mass air around '87 I think.

but I could be wrong.

What I was planning on doing was rebuilding the motor from the 86 and bolting everything from the 89 on to it and then putting it in. What I was mostly concerned with was whether the bell housing would be the same and the mounts etc. thanks Shawn

That's what I'm trying to find out?

Can you answer that?

I try to help, not burden the group.

Thank you kindly!

Wow, just read that mass air didn't come to trucks until '94-'95? Who'd have thunk that?

Yes the motors are compatible in terms of "bolting in". Swap the motors, but keep the engine control system of the '89.
