I have a 2004 single cab colorado that i have been planning to do a swap in and i cant for the life of me make up my mind on what motor to go with. I originally was going to go with a 408 with nitrous. Then i decided to just go with a turbo 5.3 at first just to get a DD goin why i was building a better motor. I then thought about an LS3 and now i'm just so damn undecided.

Any ideas on what yall would do, i'd like to do something out of the ordinary and a big block is not out of the question either.

Just looking for some input... (i dream about a cummins diesel but i dunno if i have the $$$ for that one)
