I did a 440 rebuild and on first start up the carb puked out. I ran it again with a different carb a day later for break in and then pulled it apart to check the cam and found no problems.
You should be ok.

When I started my 440 for the first time a plug blew out after about 1 minute and oil came shooting out.  Fixed that and started it up and broke it in.  4000 miles later it's doin just fine.

     When you start an engine for a break in. For the most part, you are going above 2000 rpms to promote lifter spin in their bores and proper running oil pressure for mechanical oil pumps. If you car stops running in the first few minutes, fix the problem and restart it. Immediately bring it back above 2000 rpms and finish the break in. You will be fine. Just remember proper  will have to be done with video to ensure correct tire break in.

I run them in at just under 2000 , the only chance you have is to get it up to 1800 ASAP when you restart , most of the time you will be OK , but I have lost 1 cam this way , I would use Some Gm EOS , OR the Mopar equivalent in the oil

i put eos in the engine during my first start should i put more in.  also near my exhaust manifolds there was alot of smoke coming out.  is this normal do to the new gaskets or what.

If you put the EOS in allready you should be fine. Fire up the engine and immediately bring it to 2000 rpm and set the timing to 30-35* to keep the engine cool. The oil leak is probably due to a valve cover leak or some oil spillage on the manifold when you were putting oil in the crankcase. Check to make sure that the valvecover gasket is seated properly and torqued down.

yes....    timing is a good thing to do...     i neglected mine once and had an infered thrermo on it and the engine got to 170*...    not a big deal right ?   not really...      except the exhaust manifolds were at 1200*

when i set the timing should the vacuum advance be unpluged and is that where it should be a 2k

I don't run vac advance but if you do run it just set the timing at 30*@ 2000rpm and that will be close enough for the breakin.
