Built a similar motor years ago.  Used 4X 48mm Weber IDA, and later a custom ITB fuel injected 8 stack.  Had older Edelbrock heads that don't flow as well as the TFS.  10.8/1 CR.  Cam was more aggressive 246/254 SR on a 110.  Engine is 452 4.25x3.98.  Made 600 ft. lbs. and 550 hp also. My engine needs more head and larger Throttle bodies to make more HP.  68 Mustang with full interior went 11.3 sec 1/4 mile.   These are torque monsters.  Great build.
