Alright, I just got a 1983 Ford Bronco XLT Lariat from my granddad. We've had this truck for awhile, we just haven't driven it in a couple years. Soon enough I'll be able to legally drive, and so the truck is mine! It's got some issues, though ... namely with the engine. It's got the stock Inline Six, which runs a bit rough now.
I was wondering how hard it would be to upgrade to a 302 or 351, whether or not it's worth the money/work, and if I'd really get that much of an advantage by doing the upgrade.
Plus, I'd like to know how big the I-6 is, and how powerful.
Also, what kind of gas mileage would I get with the three engines?
Thanks a lot.

Well there Airborne all 3 engines get around 12-15 mpg depending how you drive. The I-6 is a great engine with lots of torque and lasts a long time. I hate to bust your baloon but I would recommend you drive the I-6 for a bit and then consider if you need more power. Save your money for now.

Plus a 300 runs forever. If you want more power from your 300 go to www.cliffordperformance.com they have a lot of upgrades for it. I have an '83 Bronco with a 300, which is bone stock, but it goes just as well as my old truck with a 302. I drive it on sand dunes at a nearby state park and it does great. If you want more info on the engine, check out the Inline six message board. I think the more you find out about it, the more you'll like it. Also your rough idle problems could be caused by bad vaccuum lines or the carburator. The carbs on this engine are said to be cranky. If it is possible, take off all of your pollution control stuff and pull off all of the vaccuum lines except the ones to the carb, distributor, and power brakes. Doing that made my truck run much smoother and should help yours too. Keep the 300.
I've driven an f150 with a 300 and a couple of bronco's with the 302 (and recently one with a 460, but most people don't have one like that). The 300 was fine for regular duties a truck is meant for. Even towing a landscaping company's trailer. My younger brother now owns that same f150, and he gets MUCH better gas milage than I do with a bronco with a 302 (16-18 compaired to my 12-14mpg)
