How hard is it to put a 401 from a J20 into a CJ7 frame? Is this block the same as a 304?
Thanks

Can you change a lightbulb
IF IT STILL STARTS DO IT AGAIN!
Yup, it will bolt right up. Just make sure that you have the right flexplate/flywheel to balance the AMC 401 - the 304 one will not work. Other than that, it is a direct swap!! Let us know if you need more help!!

Cool! I found a 74 J20 for 250$. Body is gone but I don't need that. Will have to rebuild the 401 tho. Now to figure out what mods to do to the engine.

Well picked it up. Not bad. Set for 6 years. Has headers on it with motorcraft 2 barrel carb. Custom dual tanks. Because original rusted outAnyone need parts for a j20?
Defintely a complete rebuild. I am on my way. Hope to get the repaired frame back this comming week and put the lockers in and I am ready to start the engine. =D>

Are you sure it's a 401? Did you look under the motor mount (displacement is cast into the side of the block)? There should also be a metal tag on the front of the right valve cover with the letter "Z" on it, and the 7th digit of the vin should be "Z".
The reason I ask is that all 401s came from the factory with 4BBL carbs. Not to say a 2BBL couldn't have been swapped on, but it's just a question that needs more investigation.

Good point I will have to check it out tonight. I just took the guys word for it. Plus it was a good buy either way. Here is a pic of the top end.
