The stock 72 V-8 one should work.
The outlets should be the standard v-8 location inlet on top drivers side and outlet on pass lower side. The stock late model truck rad. may be to wide.

Summit has what ever rad. you could need for a swap for cheap!

I don't see why not, I would just flush your radiator fluid more often if it sets alot and use the orange rad. fluid!

Just don't forget to plumb in the lines off of the heads. They are used to bleed air from the system and ran into a nipple on the LSx radiators. Run a search and you will find a few solutions.
