t5->'89 4.2?

The pilot bearing in the flywheel will be different, but you can swap that pretty easy. Either the flywheel, or the bearing. I recommend you use the flywheel that matches the clutch unless you get it machined.

It will have the 2 bbl Carter bbd carb on it, but that can easily be made to behave sweetly.

As far as the T5 goes, it is a pretty tough tranny. Lasted this long eh....

I ran my T5 bone dry of gear oil on a deep woods run back in 98. I limped out to a garage with it making a really loud Bang! Bang! Bang! noise, filled it up with oil, changed the seals in 2000 and am still running it hard.

Should bolt right up using the '79's bits. The carb on the '89 is a total POS, you'll want to stick with the (not-much-better) '79 peripherals.

It's not a POS, just very choked out, as Mike said they can be made to run nice.

He's right, it is a POS. They can run nice for a little while, but always end up with s*it stuck in the idle tubes. Not a good design. The older carbs didn't seem to suffer so badly from that problem.

If you can keep the idle tubes clear, it runs great. I highly recommend reaming out the crimped end on the idle tubes like in this link:

That's true, but I think the real problem is the way the carb is laid out. Anything that gets into a BBD always seems to find it's way to the idle tubes.

The Motorcraft 2100/2150 used on the V8s has idle tubes with holes as small as those in the BBD, but rarely have an idle problem because some little piece of crap made it into an idle tube. Even with all kinds of crap lying in the bottom of the float bowl.
