novice 400 sbc build

I have a 1980 Malibu wagon, in great shape that I am spending my piggy bank money on trying to get this 400SBC in to the 12.00's. I had the block checked, bored, decked, and a line hone to square up the mains and installed studs installed.
I built a couple motors in the past and even though I'm not a complete IDIOT, I opted to have the machine shop assemble the bottom end for me. I'll be using an aftermarket cast crankshaft , and some budget Eagle rods.
The meaning of this Post is I cant decide whether to use Forged pistons or not. Probably won't be spraying the motor. And I don't race it every weekend, but I do Street race on occasion. I need help with you guys opinions on helping me decide if I should spend the extra cash on Forged Pistons or not. I'm not wealthy by any means. I will be going over this with my machinist too,So what would you do?

Hypereutectic pistons will be fine for this build check into H616cp pistons. I have built many 400 street motors with these.

you bored the engine before you bought the pistons? might be difficult to get the correct P-W clearance...
a 12 second car with a 400 is not that tough.
decent heads and cam,good intake and carb,good headers.
depending on the weight of the car??? choose gearing accordingly
Use a good transmission and a very good converter. Hope the piggy bank buys you some quality parts that will last a few seasons "at the track"
tell us about what the car has so far and we can piece it together

Forged Pistons?

The decision is really based on how many RPM's you intend to run, which is based on the heads and the cam, and if you intend to spray, turbo, or go blower in the future. Also forged pistons are good insurance against detonation. Should be fine with cast or hypers if you're careful.
