4.6 Swap?

Might be a fun project!

If I do the work myself, how cheap can I do this for?

About $400 plus the price of a 4.6 long block

Ya a 4.6 long block will do tons of good in a 94-95 d-90

Heads are different, cam won't work, front cover won't work, oil pan won't work if its bosch, etc etc. etc. Buy a short block

A few grand :-0

Short block is just the block, pistons, crank etc.

Long block includes (at least with rover) oil pan, cam, heads, front cover, water pump, rockers valve covers

Assuming he starts with his D90 3.9/4.0, what he will need to do is swap the valve covers, swap the oil pan, swap the front cover, add a cam and lifters that take the distributor (about $250), swap the front cover, get a spacer for the front pulley($30), some gaskets, a can of Right Stuff. Swap out the air management from the 3.9/4.0, new timing gear, and voila. About $400.


Ron, why would the heads not work? I must have missed something.

Serp belt heads have different bosses that non-serp belt heads. makes bolting up ancilaries a challenege if you have the wrong ones.

So basically what you are saying davis is that he needs a short block and new heads from the long block, however.

1. heads rarely are "bad" beyond what a refurb would fix.
2. Bosch/GEMS heads are not a direct swap

Now on a 97 a GEMS 4.6 long block would be ideal but 94-95 all you can really use is the short block.

what about the 4.2? can you use the same "stuff" from the 3.9? I heard (emphasis) that the 4.2 was better than the 4.6 in regards to performance????
