Well I finally got my beater truck on the road last week. It's a 78 K20 with a 400 SBC. The previous owner hacked a lot of things in it. I took it out for a drive and the first time I floored it, it wouldn't let off. Luckly there were no cars in front on me and the road was pretty straight. After a little while I was able to get the gas pedal unstuck and made it to my friends house, where I discover that I am leaking antifreeze all over the place. Looks like the seal from the water pump to the block let go. So we tow it to my house and the trucks been sitting for a week, while I am out fishing. Going to put a new water pump in, but what would cause a gas pedal to stick? By the way its a Holley 4 barrel with mechanical secondaries. I don't know much about carbs.
