That's 285 hp stock.
Bored 30 over -> around 3 HP at the crank but done mostly for C/R
Your cam is mild -> Let's say around 40 HP
243 Heads -> somewhere between 15 - 18 HP (Let's assume 18 HP)
Hooker long tubes -> around 18 HP
Injectors -> very minimal
Fast 102 combo -> 18 - 22 HP (Mostly in the top end)
So in total you should be around 389 HP. A 93 octane custom tune and you should be around 410 hp.

I am thinking 389rwhp is a little optimistic. My setup is a little wilder and barely broke 400. Granted I haven't done intake or headers yet so I'm leaving a little on the table, but not that much.

200 on top of around 389 hp that's around 589 hp at the crank not the ground. It would be 400 something on the ground. I would say definitely supercharge that thing! You won't regret it.

It's a 5.7L L59. I left the .120" overbore and 10.75:1 CR out of my sig due to length constraints LOL.
Hence the "wilder" note.
My HP number is at the ground. When you said 389 I assumed you meant wheel HP, not crank.
