1981 Bronco Engine Source
We have an 81 Bronco that has in need of engine repair. If we are headed in the direction of major expense, a remanufactured engine may be the choice.
1. How do we go about choosing the engine? It's a daily driver with occasional mudding. Currently a 302 with 650 Edelbrock.
2. What are reliable choices of one with a warranty? Fred Jones, Advanced Auto, Auto Zone?
3. Any other things that should be done at the same time (larger radiator, new motor mounts and hoses...)?
Thank you all in advance for the replies!

Call around and find the nearest Jasper engine dealer. For under $3K, you should be able to get it changed in under a week and drive out with a 75-100,000 mile warranty on parts AND labor!

It's a good idea to replace all the rubber hoses (cooling and vacuum) under the hood while you've got everything taken apart. It's really disappointing to put in a fresh motor, only to be sidelined a few days later because a rotten $2 bypass hose broke after you disturbed it while swapping motors.

WOW- you know some stuff!
Is there any benefit to bumping up to a 351? Would it match the motor mounts and the transmission (let alone the Edelbrock Hi Rise and 650 4bbl carb ?

Yes you will, but if you get an engine complete with harness and computer, you're ready to drop it in and go. Depending on the price, it may be your best bet; it beats tuning a carb on an emission-controlled engine.

So... there could be a 302 / 351 that would bolt in ? What specifically would that be ?
... and I wonder how that would affect the price!
Geez - how do you find this kind of engine ?

Jury is in, 3 of 8 cylinders are shot... Ford reman looks like the way to go $ 1,698 with 3 yr/36K mile warranty (no freight to dealer)... I will get a Jasper price to see what they have.
