350 TBI from '94 Van into a '86 Squarebody

I have a '86 Squarebody which I am in a process of restoring. Here my project thread. Currently, it got a 305 motor in it.

Someone heard about my project and offered to sell me his '94 Van with a 350 TBI and a 700r4 tranny.

The motor have 135,000 miles on it and it still runs. He asking 950 for the whole Van.

Will the 350 and tranny from that van drops right into my truck without doing any major modification? The owner of the van believe it should drop right in and that even my original driveshaft will fit.

Will 350 require a bigger radiator or fan. The radiator in my truck is still the original factory one.

I know I will need to add a electric pump but could a gas tank from that van be used instead since it already have a electric pump inside of it or it better to keep original gas tank and use an external electric pump near the tank?

Any input on this will be greatly appreciated.
