454 new long block timing questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hello - I have a 1989 squarebody K3500 cab and chassis with a 454 engine, SM465/NP205. I just bought a stock long block for it. I don't have any of the emissions on it. I added a Weiland Warrior intake designed for use with the peanut port heads. I am using a rebuilt Quadrajet carburetor (this truck was carbureted from the factory). I just got the engine to start briefly last night. I need to know what I should be setting the timing at and or anything else I need to know about getting it running smoothly. TIA!
