This is on a 454. I checked bal. at TDC and it meets the timing peg. The rotor points to #1 cyl. But the base timing is 29*:jawdrop: and total is 49*:jawdrop: at 3000rpms But it runs really good, granted this is on the trailer. It don't start hard or anything like you think it would. I'm to scared to try it out in the water. It has a 1050 Dom. sitting on top of a Holley strip intake and as far as what's done to the engine I don't know, but there is a pretty healthy cam and the heads are hogged out some and has been balanced. Other then that who knows???? what's been done to it. I'm running a #9148201 Mallory Ign. unilite breakerless optic. Is there any Ideas on what I could do to get it to 34*-36* total. It is not a locked out dist. but would like to if I knew how. I did try set it to 36* total at 3000rpms and the minute I let it go below 2000rpms it would die right away.
