Problems tuning my new motor. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Having trouble getting my new motor tuned. I have timing set to 8 degrees, did this with the vacuum advance disconnected and the motor at idle, about 8 to 900 rpm. Have carb dialed in like the Edlebrock DVD explained. Just did my first 30 mile oil change. Symptoms are stumbles on take off and will sometimes backfire through carb, definitely missing at speed. Any thoughts on what to look at, advance it more, retard it more? I made my own plug wires which I've done on my other vehicles with no problems. What's the best way to test my wires? Thanks for any suggestions...
