Drawbacks to stroking
Then you are listening to the wrong people. I would like to know what their opinion of a 4" stroke is and why they claim it is bad.
There is nothing at all wrong with a slightly under square motor (more stroke than bore). As long as you build to suit that architecture you will have a killer motor. Now, don't go and put a 4.25" crank in a 4.8L block; it will never breathe because of the small bore (Think old school 305-307). Try to keep the bore and stroke within .125" if each other. A 3.898" LS1 block with a 4" stroke is fine. A 4" bore LS2/iron block and 4.100" stroke is also fine. They will perform and last. Just do it already!

on the serious side the 402 or 408 route is pretty much worth it. 
Im thinking about 383 would this be ok for a dd? I am going to race it on weekends at the track? Would the PRC 2.5 LS6 heads work good for me with a good cam on a 150-200 shot? What cam would you all recommend?
