Hey i have a 87 f-150 XLT Lariat with a 5.0L 2wd and im thinking about purchasing a 90 f-150 XLT Lariat with a 5.8L 4X4 but could i swap out my engine and trany from the 87 and stick it in the 90 or would i have to keep the original tranny from the 5.8L and if i did can i stick it on to my 302?

Yes the 302 and 351 share the same bell patterns, but we need more info to see if the swap is possible.

What tranny is in the '87? Your choices are the C6 (PRND21), or the AOD (PRN(D)D1). It's ok to go check if you don't remember

The 5.8 in '90 could also have the C6 or another tranny the E4OD (PRN(D)21) with an OD lockout button on the dash.

Report back and we can get ya fixed up with whats possible.

Welcome aboard too.

My current 302 has the C6 in it but im not to sure about the '90 if it has E4OD would i still be able to use it with my truck?

The E4OD is controlled by the main computer, so to use it, you would need the complete wiring harness/computer from an E4OD truck.

Okay, so if i left the trans in the truck and just switched the blocks can i do that?
