I am looking at putting in a solid flat tappet cam(don't want to grind anything)so a roller is out and too much money right now anyway.The motor is a 10.75 to 1 365ci with ported Eddys(275 cfm?)w 1.6 rocker arms.The car is a 65 [Email]cuda@3100[/Email] lbs.The car has a 904 trans w/low 1st gear,3800 converter, and a 410 rear gear.The tires are 10 x 28.I have 2 intakes I can use(performer rpm & Victor 340)The carb is a 750 holley/proform dp. unit.What can I get this thing to run?Cam sugestions?

My guess is the convertor is gonna flash to low for you to hang any really big numbers up...you are similar to my little brothers car, but he is 200 pounds heavier and a point lower on compression.
Something about 620 lift(with 1.6's) and 258-264 ish would work well, if the convertor flashed about 1000-1200 rpm higher. With that size cam and your current vertor i suspect it will still run 11.30ish, well closer to 11 flat with the right convertor
