Help choosing a v8 for my dart

No again that is somebody else's Fe at the machine shop but when I was there I took a picture of it to show him of what he could have had... I showed him pictures of ones for sale for $150 and $200 at the swap meet last week.. again he doesn't take my recommendations but he pays the bills LOL.. for instance he wasn't going to rebuild the axles but I said let's take the cover off the rear Dana 60 differential and take a look.. he kept going on about how he drove it 4 hours home when he bought it and that it had to be fine... When we pulled the cover of the spider gears literally fell out in my hand or what was left of them... So instead of us rebuilding it he opted to take them to a professional and have them rebuilt. They couldn't find emergency brake cables. So one day he finally pulled the trigger on the last set that was possible to find for that year and we had to put them in.. which leads to another case in point... I've been telling him to get a $79 Harbor Freight impact drill with some socket drivers... You know to save time LOL but no we have to work with cheap ratchets and you know to take those full floaters off we have to take all eight lug nuts on both sides all the axle nuts.. I told my wife before I left I said watch this less than 1 hour job is going to take at least 3 hours and would have paid for the impact drill in my labor alone. And true to my word that's exactly what it took LOL but it was money in my pocket instead of Harbor Freight...
You can lead a horse to water...
Gotchya. Let's stop the sidetrack. LOL
