ok, i have a 302 from an 89 gt installed in my 68 coupe. i just acquired this car last weekend and it has a few minor issues that i would like to hammer out. i am not an expert when it comes to carbureted engines, but will be learning as i go. the engine is built with the following components or so i am told. lower roller engine including heads, block , crank, pistons, etc.... non bored engine. weiand street warrior intake hedman ceramic full length headers demon carb with spacer, road demon 725 i think. dont know how to tell..... ford racing X303 cam MSD distributor, with ford racing wires, 6AL ignition control, and ACCEL coil. the problem i am having is that it tends to want to die at stop signs occasionally, although sometimes it idles fine. i idle it up slightly and it doesnt want to sit in drive without surging. (2500 stall) and also wants to die when in park as well. basically doesnt want to idle very well. it also has a slight miss when under hard acceleration, kind of a thump thump in the exhaust note. but it does run extremely well otherwise, pulls very hard and runs very, very strong. any tips or advice would be appreciated, im wondering if its just too big of a cam? can i jet the carb and improve all the issues?
