Default No spark with rebuilt motor

So I have been working slowly but surely at getting this thing back together. 383 200cc AI heads solid roller. New MSD pro billet opti new msd coil new msd 6AL ignition. The ignition is 100% wired correct. I am getting no spark though. Everything turns over nice I am getting fuel because the plugs are getting gas on them but it won't ignite. I tested acouple plug wires for spark with a spark tester and nothing. I can't figure this out. Does anyone have any ideas? Any help would be apreciated

Ohm test your coil and wires as well as having the ICM tested. AutoZone will do the coil and ICM for you and you can ohm test your wires easily with a volt meter...

she lives. stupid mistake forgot to hook up a coil wire. ill try and get some videos up soon. What do you guys think on mufflers? I have 3" dynomax bullets with an x pipe but I don't really want it to be rediculously loud.

That should be plenty loud, haha. I had a 96 GMC shortwide with a 94 LT1 in it. I had longtubes and the Flowmaster Super 40s on it (The Super 40s were new back then and I wanted to be the first kid on the block to get them) I really liked the way it sounded. It had a little more drone on the highway than I was looking for, but it sounded so good when I put the pedal down

Aaahhh... I wish I still had that truck. It was usually a big PITA, but it was something that few people do, and I really enjoyed that part of it. Hope you like yours!

I think even 2 flowmaster 1 chambers in that true dual exhaust would be a little more quiet. So I would go with anything thats an actual muffler (hooker/flowmaster ect.) as opposed to just a baffled bulge in the pipe (bullets/sweet thunders/spiral flows)

I know its a cookie-cutter thing to do, and you may not be into that, but I really really like the super 40s I had on my truck. They weren't too loud at idle, but they sounded awesome when you put the pedal to the floor. If my car wasn't lowered, I'd like to find a way to tuck them on a true dual system on it. They're pretty big mufflers, so it might be ruled out on an F-body at stock ride height. Maybe I'll just put a lift kit on my Camaro and install them

i had one flow before and it sounded good but with this iono the cam lopes hard even at 1000 and i think a flow would sound akward at idle. maybe im wrong? I have long tubes and true dual 3" with an x pipe. i haven't got any muffler videos but this is it straight headers running a cylinder down. http://www.youtube.com/watch?v=9M3chFdjydQ (may not work for alittle needs to be processed)
