need help with my carb

[302crew]

well i have the gauge and the pressure is set i need to know how to tweak out the carb basicly like right now i have the sight bowls at about half way becouse there the clear ones and i have the 4 screws on each side of the bowl turned a turn and a half out from the bottom and the timing is set at 14and the fp is at 7 heres the thing when im beating on the car and i shift it into 5th it dies has no power and also when i downshift and go it bogs hard before it goes. could this be cause my motor didnt fit under the hood so i just cut a hole in it temporarly and its getting to much air or 2 could my valves be out of adjustment and 3 i put my cam in and lined the two dashs up by eye and here is the thing my cam card siad these specs are for a cam installed at 108 intake center line did i install the cam wrong.
