Engine Swap

[Holmsey]

Hi I have a 93 LS400 engine fitted to my 1960 F100. I also have a 95? LS400 engine. If I use the inlet, fuel rail etc from the 93 is the basic block the same? Reason is I have the ECU all wired and running on the 93 but tappets rattle and leaks oil from rockers. So thinking if the block heads etc is the same I will just bolt all the 93 stuff on it. Oil tight rattle free engine.

Your newer ecu is still old and may suffer from leaking capacitors (refer to this https://www.clublexus.com/forums/ls...exus-issues-solved-ecu-leaking-capacitor.html)

Fuel rail, heads, intake will bolt up from 1993 to 1995. Engine loom and ecu must be different though. a/t harness , connectors, and number of solenoids might be different too
