What do I set my timing at? 350 with TPI - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am setting the timing on my truck. I just put my TPI on my 350. Usually I set by sound, and then cruise around and make sure it isn't pinging, but I want a ball-park figure to set it at.
Is it any different with the HEI and TPI on it?

disconnect the tan-black wire connector & set it @ 0*. turn engine off. disconnect batt for 30 seconds to clear the code 43. reconnect wire & batt. install bed, open gate, start engine, put in D, drive down here, do burn-outs!
