distributor installation questions

So I need to put a distributor in my 4.2. The previous owner had taken it out. Is it as easy as sticking the new one in and screwing it down?

Anything need lined up?

you have to align the dist correctly when cyl 1 is at TDC or your timing will be off.

Yup, what Sentinal said. And maybe the oil pump too.

After the #1 piston is at TDC, it pretty much pulls out, however you may need to twist it a slight bit to mesh the gears.

I just installed a new dist. I pulled the dist. cap exposing the rotor then manually turned the pullies untill the rotor was at a 90 degree angle to the block then pull it. I did need to use a long reg. screw driver to rotate the slot on the oil pump in order to insert the new dist. Put it all back together then firedit up a reset the timing. Be sure you put the rotor on your dist. before you stab it so you'll know it's in right.

should have the new dist. tomorrow. Sounds fairly easy but still makes me nervous as I haven't ever done something like this before.

I bought the jeep and the motor was missing the distributor and vavle cover. The valve cover is a no brainer but all the vacuum lines and air intake look like it might take some time to figure out how it all goes back together. Worse case scenario I will put a weber on it and forget about it

Ive never heard of anything like this. How do you expect to start your car when your done if it hasnt had a valve cover on.

Obviously i'm going to replace the valve cover before starting it. The valve cover and distributor were stripped for parts to get another motor running.

Do you have a Haynes or Chiltons manual for it?
It should give you a step by step for the distributor.
As far as the vacuum lines...someone here with the same year and motor could maybe take some pics for you.

Yep I have a manual so I think I can figure it out...I hope. I'm pretty handy but this engine work makes me a little nervous.

I really hadn't looked at any aftermarket stuff. What are the benefits of the HEI?

an engine that runs much better. seriously the HEI upgrade is probably the best mod you can do to the 4.2 short of a FI conversion.
