383/400 stock stroke recipe's!

'78 400 with forged 383 crank, H beam rods and ARP main studs, KB 240's zero decked. I have a Holley street dominator intake and a performer 383. Also have an Offy tunnel ram with a single quad top that I want to convert to a ram jet style port injection intake. I am considering stealth heads but not sure how I will complete the motor yet. Going in a '70 Dart with a four speed.
