To lock out my distributor or not? Mallory unit #919691 02/02/11 02:42 PM 02/02/11 02:42 PM

I want to re-curve it this off season as out of the box it has a huge total advance sweep of 28 degrees. I am looking into buying the Mallory kit that comes with springs and a set of advance limit gauges. I plan on installing a NOS Sniper system either this season or next and was recommended to lock my timing in at 20 degrees while on the spray. The motor is 10.5:1 compression with iron heads and runs on pump 93. Should I just go ahead and lock my timing in now or wait until I get the kit? If I lock it out, could I have issues with detonation? I just want some insight. I could just experiment with it but can't drive it here in Michigan for a couple of months so figured I would ask. P.S. Here is my cam spec if it helps any cam spec Ryan "Bigs" '73 Duster (BLKDUST) - Black, 100% factory sheet metal, flat hood, 346 cid, J Heads, and a bench seat. http://s268.photobucket.com/albums/jj1/bigsbigelow/ Best to date: 12.40 @ 109 mph

Probably will get a MSD timing control and 6AL when I get the kit so I can adjust the timing a little easier. Maybe just get one of these even Mallory Hyfire Ryan "Bigs" '73 Duster (BLKDUST) - Black, 100% factory sheet metal, flat hood, 346 cid, J Heads, and a bench seat. http://s268.photobucket.com/albums/jj1/bigsbigelow/ Best to date: 12.40 @ 109 mph

With technology advancing so quickly these days it might be advantageous home of the Sox and Martin Hemi Duster
