let me tell you my set up before i get into the questions. engine is a p code 400 from 1978. meaning its the high performance 400. ive got a mopar m1 singleplane intake, carter thermoquad (unsure of cfm i think its a 650 tho) freshly rebuilt. when i got the car someone had converted it to points. i converted back to electronic so i could put my orange box ignition on. (this box has been on at least 4 cars since the late 80s). there is a 4 degree advance on the cam. also a 1 inch spacer under the carb. running hooker comps straight into flowmaster super 44s at the moment. trying to get her dialed in to a point untill my shifter comes in and i can drive her. NOW to the problem. A: my little plate that mounts to the timing cover for the timing light is non exhistant... B: by ear the timing seems pretty close to dead on. (i know i know never time by ear but i actually have a knack for it and can usually get it dead on... theory tested with a light after setting up by ear... not on this car tho obviously) but when the secondaries open up the engine either seems to be starving for fuel/ or the timing is off... seems more like choking to me. runs a little better when vaccume advance is removed but still seems to be starving for fuel... now it does have a brand new fuel pump and filter after flushing out the tank and lines. filter is installed properly. excellent throttle response... untill you hit the secondaries... any ideas? carb to big? needs adjusted? if so what? do i need to adjust the air metering rods? or the accellerator pump pin? anyone have an idea on how to read the timing with a light without the scale attached to the timing cover? i knwo alot of questions but i am a little lost here. HELP!
