I'm putting an edlebrock c-26 dual quad intake with offy cross ram adaptors and two 600 cfm edlebrock AFBs on my 283...but I'm totally nuts.
Also got a comp cam, roller tip rockers (1.5 intake and 1.6 on exhaust), new timing set, reworked power pack heads with 1.82 intake valves and hardened exhaust seats. I plan on using a progressive linkage and will dial in the carbs with new rods and jets.
