This is just the opinion of someone that has been around for awhile, listen, or don't it's your choice.
There are 2 big topics that seem to be brought up over and over. "Top Swap" and "Next mod."
Top Swap:
Just some quick advice from someone that has been around for a long time, and seen a lot of builds: If you are wanting to take a NA engine, and do the "top swap" you are better off staying as close to stock as you can. I have heard of too many people do a build with the NA bottom end, and destroy everything. The compression ratio for the NA engine is higher, and the components are weaker. There is a reason GM used 2 different bottom ends for the 2 different engines. The NA engine was not made to be boosted. Keeping that in mind, it can be done, but should not be more than just a swap, and tune. In other words, when you start talking cam/rockers etc, you need to think about that bottom end. In my opinion, it will be way better/reliable/faster to just do an entire l67 swap. That may just be my opinion, but again I have been around the 3800 community since it started, practically. I have seen a lot.

Next mod:
I have read what to do next probably 100 times. It is a very good question. There are a few things you need to figure out yourself before you can ask this question:
How fast do you want to be?
Your budget?
Your skill level?
Streetable or no?
You need to figure all this out before you think about modding.
Warning: Modding is addicting, once you start you will not want to stop. You need to set a limit from the start. Unless you have more money than you know what to do with. In that case give some to me.:icon_lol:
The #1 most important rule to follow: Do it right the first time so you dont have to do it again later.
Something to remember: Cheap/Fast/Reliable---- Pick only 2.
