Forced Induction 93 with HCI. Getting ready to supercharge. Anything I should upgrade internally first?

Sort of an immediate gratification leading to a long term goal question:

I have a 93 5.0 with Trick Flow HCI, but otherwise stock internals. Currently around 130K legit miles (not one of those guys who claims 30k just because the 5 digit odometer rolled over, lol), and the pistons and everything else is in great shape. Car hasn't been run hard or abused, and it's my daily driver several days a week. Last dyno it made exactly 300 rwhp and 333 torque. I'm getting ready to put a Vortech V3Si on it. So, is there anything I should upgrade inside the current block )...or should I just seal it up good with new gaskets and freeze plugs, install/tune the SC, and run it like it is? I know the stock block will be the weakest link in this combo. That's the immediate gratification part.

The long term goal (while I'm driving the previously mentioned setup) is to get something along the lines of a Dart block that I won't have to worry about splitting, and slowly start acquiring better crank, forged pistons, etc to build a much stronger motor. I figure this will take me a year and a half, maybe 2. Then once I have all the parts for the second build, I plan to pull the motor, swap everything I can from the current motor onto the built one, and run that without worrying about splitting the block.

Thanks!

Thanks! Been busy and don't post much on forums. The motor is open now because it had some odd coolant leaks I couldn't find, and also wanted to fix a leaking rear main. Heads are off as well to check and see if they weren't warped, because I popped a coolant hose and overheated it fast awhile back. The coolant leaks weren't from a blown head gasket, and the heads are fine. So I'm going to have the shop check everything and replace all the original gaskets etc before putting it back together, then install the SC and tune it. Yep, scouting for an already built motor is a good idea too. I'm just wary of buying anything used, so for my peace of mind I'd kind of like to just start with new parts without any questionable history.

and I agree that putting beefy internals in the stock block is kind of a waste of time, as they aren't going to save the block if something goes sketchy. That's why I was leaning toward just new gaskets and freeze plugs and put everything back together the way it was before
