We have 340 0ver 30 with 10 to 1 j.e. slugs stock forged rods and cast crank that i was told not to worry about. this motor has 360 heads 188 160 valves 480 480 comp cam edelbrock ld 340 intake. electronic ignition 727 and I have 456 gears for the back. I want opinions on cam selection im leaning towards a good hydraulic and I have the 273 adjustable rockers and push rods, heads (I want the eddis) , and carb size. I want my 67 cuda coupe to run 7.50/11.50. don't be afraid don't hold back I need your input.

Your goals are easily attainable. 400HP will run mid 11s all day. Your cam is a little weak, would consider the .508 hyd, or equivelant solid. The problem is the "street" part, depending on what you can live with. My car with 380HP and 3150 weight runs 7.35 @ 91 in 1/8, 11.60 @ 114 in 1/4. That's with 4600 stall 8 inch converter. Same package with a 2900 stall only ran 12.30 @ 108 in 1/4. The converter and chassis setup are key to get where you want to go.
