Whats new? I am trying to help out a friend right now get his car running. Just rebuilt engine (by a reputable builder), new Holley carb, and new MSD HEI distributor.
I got the engine @TDC last night(felt the air coming out of the #1 cylinder), checked the wires 3x and made sure there is fuel and spark.
The engine will not start but one hellva blast comes out of the tailpipe. It did this a few times as I was trying to rotate the distributor to get it to start. Usually when I start an engine for the first time I get a small "backfire" out of the carb while I am getting the timing right butit usually starts by the second or third try. And most of the time the engines will start. I never had a blast out of the tailpipe, so I'm kinda confused. Also I am used to the engine showing some kind of life after the first revolution or two, this engine turns over 10x or better before I get the gunshot out of the tailpipe.
I am fairly sure the timing @ the distributor is correct in relationship to TDC. Is it possible that I am missing something here? How about the timing chain being off a tooth or two? Any suggestions? Its his first car build and it'd be great to help him out but I never had this much trouble get an engine to fire over.
