Sounds good except for the Max Wedge port size in the 440 Source heads. That modification will give you nothing but trouble. There isn't a valley pan gasket that fits the larger port size and you can't really port a Victor intake to Max Wedge size so that plan isn't going to work. Stick with the standard port size and you'll have plenty of power.

I built that same engine pretty well. 383 with steel 440 crank, Eagle rod 10.0-1 compression with Diamond flat top pistons, Eddy rpm performer heads and matching intake. All Out of the box. Lunati solid lifter cam .544/.566 .243/.251 @.050 AED 750 HOM carb will flow to 830 cfm, motor only used 638 CFM on the dyno. 1-3/4 TTI header as they dont make a 1-7/8 for a big block A body. 32 total timing, pump gas made 525 hp and 552 tq, has good manors runs nice on the street with 3.73 gears and a 3500 stall.
