Why can't you use the pulleys from your current engine? Serpentine is nice, but not necessary (and IMHO stay away from CS130 alternators).

Without taking it apart you will have to use an electric fuel pump.

I don't think I would do anything special other than prime well with a drill and rotate the crank a couple times while doing it. It looks pretty clean to me.

I would not do anything with plugs?

Also, this is not a roller cam engine. Be sure to use a high zinc oil and follow the break in process to the letter.
Staying away from the CS series alternators, gonna try and stick with the 12si I(94 amp) just got.
Now that you mention it I see that those center holes threads are at a different angle... Any idea where to get those shims/washers? I'd rather not hog out the holes in the intake if I don't have to.
I'm going eventually add A/C so I was trying to plan ahead and get a long nose water pump which means my current pullies will be un-usable.
I was also planning on using the Amsoil "break-in" high zinc oil, How do I prime it with a drill? Again newbie here. Thank you for the reply and help.
