Let me tell you what I am dealing with. I have this truck 283 with holley intake and edelbrock carb. The man I bought it from said it had a cam in her but it was not anything huge. But he was not sure what it was. So my question is what should the timing be? I am running an hei. It has a new timing set so I know that is good but she pops a little through the carb and runs like crap when you try to drive it. She runs great when you are just idling and revving. I know its just a little timing problem but just not sure what the timing should be. Any help would be great. thanks:
