About intake...

-74 400 Magnum, gets following parts: cam from 440 Magnum, stock pistons, aluheads from 440 Source and exhaust manifolds from 440 Magnum. Car is full-steel -66 Dart 2d with TF727, stall about 2500rpm, 3,21:1 rear and 295/50R15 tires. Maybe 275/60R15...

I have 2 choices about intake; Edelbrock Performer with 650cfm carb or early Offenhauser 5196 for 3 Rochester 2GC... I guess, that Edel would be much easier to get tuned, but 3x2 would look just great... :-D
