Like Kevis says, 280 degrees of advertised duration is a lot of cam for a 305. Are you planning on using full length hedders, cylinder head work (screw in studs, springs a little port work), manual transmission or an automatic with at least 2800 rpm stall, plus some carburetion (at least 700cfm)? Remember that a larger cam will be more pronounced with less displacement. I switched from a 280 comp cam to a 284 extreme energy cam when I built my 383. If I stayed in the 350-355 displacement range I probably would have opted to use a 280 comp cam. Probably a 260-268 comp cam would be more to what you're after. You can maintain the dual plane intake manifold, don't have to mess with the heads, can probably use an off the rack Q-jet carb and don't have to mess with timing curves. Take a look at the engine in my signature. I can use all of that cam you want to install and that motor has more displacement. I maintain 16 inches of vacuum at idle, out of gear using an 830 holley chokeless race carb with 4 corner idle and the alum cylnder heads have a standard race port from Air flow Research with 2.05 intakes and 1.60 exhaust. Another option would be to just throw the stock 305 in and put more dollars towards your big block.
