How much difference does 25-ish years make?
In my 67, I yanked out a rebuilt, with approx. 10k miles, 300-6. There's a tag, from somewhere in Pennsauken NJ where it was built, and was bored .060, rod and mains both ground .010
Now if we wanted to put it into a newer truck, like my 94 ( ain't gonna, mines all original w/ under 50k miles) could we use the newer FI head? Is there any benefit to using the newer head? Would probably convert to a 4bb anyway....And other than the **** for the manual clutch linkage, what other major differences are there?
My buddies got a truck that needs a motor ( 94 f-350 dually flatbed), and I got a motor that needs a truck
In any case, would the 67 oil pan fit my 94? Mine leaks and is quite rusted, and both are 4x's if that matters....
Thanks!!

The 300 block changed very little throughout it's lifespan. I believe the biggest thing between carb'd and fuel injected is simply the fuel pump opening for the carb version is blocked off on the EFI.
If you are going to put the 67's 300 in the 94, the head choice will depend on what you want to do with it. Use whichever head is oriented towards what you want to do: the EFI head for EFI and carb'd head for carb'd. They flow differently and perform for the system they're made for. IF you're going carb'd and want to do a performance upgrade, you can put a 240 head on it to get some extra compression.
In the case of the oil pan, I know they changed shape a couple times throughout the years. They used one oil pan for 65 - 79 to shape around the solid front axle. The shape changed completely in 1980 due to the TTB up front. They used this shape from 80 - 82/3, and then used another shape from 84+. I think the last change was due to an upgraded oil pump that was a different shape. They had the same front axle setup from 80+, so it wasn't due to a frame difference. Unless the truck is lifted, I think you'll run into axle clearance issues from the 67 to 94.
I don't *think* you can put a 94 oil pan on it because of the oil pump, but you could probably put an 80 - 83 oil pan. It'll fit on the 67 engine and cover the 94 axle. Looking at www.rockauto.com, the oil pump looks the same on a 67 as it does an 80 - 83. Looks like it should work.
If someone knows more about this, they'll probably chime in.
