World Products V Dart Little "m"

[mazspeed]

Ok fellas. I am looking around at crate engines from World products 427 small block, Scott Sharioff 434 small block and Smeding's 427 Dart small block.
Here are the pages for each but Smedings 427.
Worlds
Ultra streets

Now I'm going to the Goodguys show this weekend to check out Smeding's 427. His is the most expensive, as the taxes and everything else, but he said he would work a deal with me. I'm also going to look at other engines there as well.
The World's 427 seems to be the best priced and the Ultra Street has the most power and also a good price. All seemed to be helpful. Now without seeing the specs on the Smeding engine, what would you guys go with? I'm still looking around for a good deal as I need to make a decision by Monday so that I don't keep CAR held up on my project and others that they have going on.
