349 CI on the cheap

This have been a great thread, I have been torn as what to build for a future motor for my 64 Valiant, since I already have a 72 318 in the car your alls recipes will help me build a great engine for street use. The current engine is a .30 over 318 block , with 3671587 cast head, with 1.88/160 valves, mildly ported, 340 factory Mopar purple cam, windage tray, LD4B/600 cfm, pertronixs, with factory exhaust manifolds....all that gave me a whooping 225 hp with 275 LBS torque.....Wow, with what you have out lined.......I could break the 400 hp mark and scare the **** out of myself.........all with a 318........
