Yes, the 5L is a 302, the 5.8L is the 351. The difference is cubic inch displacement. The 5L will get a little better mileage, the 5.8L makes more torque for towing. Since you probably don't ever pull a trailer, it won't make a difference. I'd say look for another one and keep your old one for spare parts if you have the space to keep it around or have someone help you strip off all the good stuff and get rid of the rest. I had an 87 interceptor that had a bad electrical system but the rest was good so I stripped the running gear and donated the rest to the local fire dept to use for extrication practice. Whatever you decide to do, Good Luck!
