Crate Engines Looking for some advice

[b757jetdr]

Hello Everyone!

I am starting to do my homework on crate motors and thought I would ask for any info/advice/opinions! I have been looking at alot of different motors. I am leaning toward two of the GM LS3's the 376/480 and 376/525. I am looking to keep cost in check so I can keep the project moving and get it on the road soon. Figure I can always mod the motor some winter after car is on the road. I am trying to balance wants/needs/ and what needs to be done during fab and paint vs what can be done bolt on after car is up and running.

So guys let me have it any ideas on where the best place to go to buy and which ones to look at?
