93 4.0 swap using 258 parts build help needed
Well my old 1981 258 engine is toasted due to running out of oil and I can pick up a 93 4.0 engine out of a grand for a good price.
I have read the official 4.0 swap thread but it doesn't really cover what I want to do.
I am getting the full 93 4.0 engine but due to time and money constraints I plan on using my '1986' intake and Carter-Weber BBD carb on it. I will save the FI intake for a later project. I read the grand isn't the best harness to use anyway.
I know I need the exhaust manifold and a chunk of down pipe to hook that up and will need to trim the intake a bit some place right?
Is there a good RTV to use or what intake gasket should I be after? Mine is about 10 years old.
The engine has no starter or alternator. I figure I can use my 258 flywheel and starter ok.
I figure my waterpump and fan can swap over.
I also figure my engine mounts will swap over.
I will need a new pilot bushing or can I pull my old one and swap it. Any part numbers on that?
What else do I need?
Can I use my AC Delco alternator and my PS pump? (engine should also have a PS pump on it, but a serpentine pulley)
What about the crankshaft pulley? Will my V belt one from an 81 engine swap over ok or are there gotchas?
Then there is the distributor. I read that someone used the 4.0 distributor but can't really see that working or? Will the 258 one swap or??
I will also need an electric gas pump, 'shudder', what type is best? I will want a self priming one with low psi I believe. Suggestions? I have the 20 gallon poly tank on it so will go inline for now.
I do know how to wire it in using the oil pressure sender and fender solenoid's side posts for power so it will see power in start and with oil pressure.
Anything else?
