The most common reason would be a ruptured oil cooler in the radiator. Check to see if you have oil lines going to the radiator, if you do, you need a radiator. Also, don't forget to change the anti-freeze because it will be contaminated. Don't forget to check your transmission for contamination also, as Transmission Fluid also runs on the outer region of your radiator to cool the transmission fluid.

What would cause oil to leak into the antifreeze reservoir on a Chevy Venture?

If it is motor oil in the anti freeze, then it is either a cracked head, cracked engine block, or a head gasket blown. If it is transmission fluid in your antifreeze, then the radiator is leaking from the transmission cooler ----- although usually that would cause antifreeze to be in your transmission fluid.

Will a 400 engine from a 79 Chevy truck fit into an 89 Chevy truck?

It could, but why would you want to? From 87 onwards, Chevrolet went to Throttle Body Injection (TBI), which was a far superior system to carburetion. IMO, you'd be better off to drop in a TBI big block (the 400 was a small block, and ceased production in 1980, long before TBI became a thing).
