Engine Swap need help
Ok I need some help making the correct move here.... My daughter has a 1978 F-100 w/a 302 and launched a rod....The engine is toast. . Here's my question...I am on a very tight budget...Should I get a long block out of a donor truck (same model about $300.00) Or I have found a mid 90's explorer with the H.O.302 for 400.00. I will convert it over to carb. What else would have to be changed. Will the oil pan be ok and what about the cam and dist., will the ones off the HO be ok with a carb??? Any insight ya'll can give???

Well the long block with all your outer parts would be the quickest swap as I see it.
2wd eng oil pan is a front sump and 4wd oil pan is rear sump. To change it you need a different pan and pick up tube.
Can you at least get a "run warranty" on the 300 dollar long block? The HO 302 is out of a ? Motor mounts, external eng pieces compatibility? Converting to carb and figuring out the rest might eat up more time.....

Going from a 302 to 302 should be a straighforward swap.
Running the older motor will be quicker - all the accessory mounts and stuff should be almost identical - swap over the stuff you need, plug it all in!
Running the newer motor would be better - the heads would flow better, and the whole thing will have more power & efficiency. However, you might spend more time swapping brackets from one motor to the other. Plus, you'll have to put the carb manifold on. There may be other little things as well (extra sensor ports to plug, etc)
Motor mounts should all be identical from all years 302, if that makes any difference.

I was just brain storming with out a brain and hitting on 5 of 8 cyl, thought maybe the HO eng may of came out of a car and mounts and oil pan might be different?
I think we have his ? covered.
