Hey guys this guy wants to sell an engine off his 85 300 and i don't know if it will be compatible with my 89. Please help thanks

Aside from some differences in ECU tuning the engines should be pretty much identical. Suggest you take the ECU with it.

Your 89 had a "W" series VG, slightly higher compression, full float wrist pins etc. Yes you can run the 85, no you won't need the computer if you run your injectors and oxygen sensor and mas. To run the 85 computer you need the 85 injectors, O2 and MAS.
