289 ==> 302 HO Engine Swap Pointers?

[ducsingle]

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.

Clutch arm might be different from your setup to the 302.

What clutch arm should be used with a 302?

. . . . waterpump might want to be swapped over along with the pulley.

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?

There was an article in CAT newsletter in 2009.. i'll try and dig it up later.. think it listed the parts needed and part numbers.

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.

That would be extremely helpful.
