Newbie Question.....

Hello,

I am a newbie here with a newbie question:

I have been reading this site for about a year now and finally have the opportunity to buy not one...but two cherokees!

Unfortunetly I have to choose between the two and here is the question....

One of the cherokees is 79 with a 401 and the other is a 82 with a 360.

Is there a substantial advantage in the performance and drivability between the 401 and the 360?

Also...is there an advantage getting a 79 rig over a 82 rig? (parts, upgrades..ect.)

Both these rigs have a little bit of rust....are there any good rust inhibitors that you can recommend to help stop the rusting and what is the best way for them to be applied?

I appreciate the advice and look forward, one day, to putting a pic of my new cherokee up on the board!!

Without seeing it I would still opt towards the 79 with the 401. IMO I don't think there is an advantage from a 79 over an 82 other than clean interior, paint, and rust. POR15 is awesome stuff for rust. Get the 401!!

I believe that the 401 was only available from 74 to 78, so either the guy is yanking your chain about the engine, the year, or it may have been swapped in. I have a feeling that it will be unanimous that most everybody likes the output of a 401 much more. There is even guys on here that are sticking the 401 in the 86-91 Wagoneers. If the condition is similar between the two jeeps, I'd lean towards the earlier one.

Welcome aboard. I don't know enough about early Cherokees to answer your question. As to rust, I have heard good things about POR-15.

Thanks for all the info....

How much horsepower does the 401 compare to a 360?

What is the gas mileage on a 401 compared to a 360?

Are there any major differences in maitenace on the 401 compared to the 360?

Last but not least...is it smog legal in the state of California?

Thanks again...

The HP of the 360s changed depending on the year. No mater what the year, the 401 had better power out of the factory, with 215 and 320 ft-lbs of torque. Check out the tech section of this site http://www.ifsja.org/tech/figures/engines.html

The mileage depends on how you drive, but when I had one it was about 10-11 mpg, while my 2-barrel 360 got around 13.

A 401 is basically just a bored-and-stroked 360, so other than the parts required to give it larger displacement they are the same.

They are smog legal as long as they have whatever equipment was required for the year vehicle. Since they look the same outside, you could put one in a newer FSJ as long as all the smog stuff from the newer vehicle was reattaced. The smog people would never know without seeing the number stamped on the side.
