318>390 Stroker.......Your thoughts

Thanks guys. I'm happy to read anyone's thoughts and thank the guys that take the time to put down long constructive answers.
The aim was always something that would be circa 400HP and mid 400sTQ. Ideally wanted the car to run in the low 12s but be streetable. Understand you may have to compromise on some stuff and I would drop HP for TQ as that part of the power band is where It will realistically be driven most of the time.

Engine hasn't even been to the shop yet for work. No point until I have most of the parts to allow it to be completed. I have the heads, crank and rods. Pistons, cam and the rest of the rotating assembly is on back order.....waiting game.
