t5->'89 4.2?
 
I have a chance to get a 4.2 from an 89 Wrangler to replace my tired 258
in my '79 CJ-7. Will that bolt up to the T5 I currently have? ( I know
I should replace it while I am at it but limited budget dictates)

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.
