First question you need to know, is this car going to be operating on non-leaded pump fuel? If so, you'll need to use a cylinder head with hardened valve seats. If you want 400+ horsepower out of a 350, I would recommend a set of Edelbrock heads along with an Edelbrock or Holley Dominator intake that can be ported to match the heads. By the time you prep a set of OEM heads, you would be further ahead with the Edelbrocks. Add a set of forged pistons, camshaft that would make power to 6500-7000 and upgraded valve train with beehive springs. Don't forget a good set of 1-3/4" or so headers and free-flowing exhaust. I would use a race-prepped Q-Jet but that's just me. If it's a street car, a minimum of 3.91 rear gear out back will be required.
