I bought my Dakota in July and subsequently found that the whole thing was full of sludge!! One of the rocker arms was off and just sitting in the head. Some of the valves were sealed shut because of sludge. I pulled the engine and took it over to the local engine shop to have rebuilt. They bored it over and put some new HD cams, etc..in it. Looks nice and runs great!! Pretty excited!

Here's some before and after pics. I should have taken more, but I was in a hurry. The sludge was ridiculous!

Let us know how she runs with the new innards.

 

Thats a sexy engine!!

Nice! I like the valve covers, lots of new parts how much did the rebuilt run you? Also what was the HP increase? If they dynoed it.
