Timing Problem!

your timing should be the same, you should check it with a timing light...now im guessing you have a computer controlled car and you removed some o2 sensors and converters.
so your timing was always off, the way you posted it I assumed you installed new exhuast and then the timing was off, set it up with about 14 degrees intial with 32-36 advance all in at 3000
because the car turns off and the idle os off. the guy at the exhaust shop mentioned to me that when ever you have a new engine, and you apply new exhaust to it you usually have to adjust the timing to match with the exhaust. It seems as if the engine is being smothered by the exhaust. Before it was just running just off of the headers alone and it fired right up and ran correctly.
sounds to me that your running rich and fouled your plugs, you should check them...the exhaust man sounds like an dumb *ss, it has nothing to do with your timing
1. what kind of distributor?
2. what kind of carb? if it's a CCC carb then not having the O2 sensors will affect timing
3. buy a repair manual and a timing light. retime engine. or there's the redneck method--advance the dist by ear until you have the best idle. now snug--do not tighten the dist hold down bolt and drive the car retard the timing until you get the best performance.
it is true that when you put a performance exhaust, especially headers, you need to adjust the timing. the exhaust scavenging will affect the intake charge, which affects the air/fuel mix which affects timing.

unless you have a pretty radical cam, i don't see the exhaust messing up that timing to the point the engine just shuts off, mine stayed the same after i put a real exhaust system on.(headers with extentions and turn down before) but im assuming that you really didn't drive the car that much after the motor swap, so i guess you should do both
