Hi i'm considering purchasing this motor http://www.hmotorsonline.com/s...30021

I just had a few questions, I know it works with my tranny because it's d-series...but what else will I have to worry about? Im having a shop do it because I don't know how to swap an engine out, he said he woould charge me 400, would there be any hidden things he might charge me for?

Also, Is the engine good? I've heard parts for them are hard to find...
