I am not sure if I need to use a different radiator or cooling system. Is this going to be a "CAN O WORMS?" or is this a okay swap? Thanks for any help.

I would expect the 400 to possibly require more radiator.

It's true. I really don't do anything but browse the Internet looking for trouble... | | | | | Joined: Mar 2004 Posts: 3,068 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 3,068 | the 400 is externally balanced so the balancer and flywheel/flexplate have to be balanced. It's a specific to the 400 thing,
Scott | | | | | Joined: Apr 2010 Posts: 436 'Bolter | | 'Bolter Joined: Apr 2010 Posts: 436 | I had a 283 in my old '63 C10. I swapped in a 1974 400 in 1982. I had no trouble just bolting it in. everything matched up and went in with no problems. I didn't even have any cooling problems using the stock radiator from the 283.
Like 48BigTrucks said, you MUST use the flywheel/Flexplate from the 400 because they are externally balanced. That's the only difference you will need to worry about.

Reason: you cannot use stock 350 heads, unless you drill out for steam holes in the 400 block. You may need a new radiator and definately a fan shroud, since the 400's tend to run a little warmer. Other than that, it's a good swap. | | |
