Default 289 ==> 302 HO Engine Swap Pointers?

I'm considering swapping in a 302 HO (roller cam) engine for my current 289.

The 289 broke some pushrods several weeks ago and will need to come out for repairs. A friend has offered me a free 302 HO engine, which has some advantages over the 289.

I've heard a 289 to 302 swap is not plug-and-play. More specifically, I was told the following:

*the 289 timing chest cover needs to be installed on the 302
*the dampener setup needs to be changed
*the flywheel pressure plate needs to be changed.

The timing chest cover is a no-brainer, but I would like to get more details about the dampener and flywheel pressure plate changes - - - and anything else a 289 ==> 302 swap requires.

Is the 289 a 5 or 6 bolt? Clutch arm might be different from your setup to the 302, waterpump might want to be swapped over along with the pulley.

The current 289 is a 6 bolt.

What clutch arm should be used with a 302?

Now that you mention that, I recall reading the same thing somewhere. I think the reason was that the 302 water pump outlet is in a different position that is not ideal for routing a hose to the radiator?

Going from a 260 to a 347 roller engine. Click on each pic for information and discussion.

Thanks. That's a fairly extreme build, so I'm not sure what might or might not translate to a relatively stock 302 GT40 engine.
