Fired it up for the first time and it seems smooth and strong. It starts right up with the breather off, but with it on it just doesn't want to fire up.....suggestions with the new edelbrock 1406?? or should it make no difference and its just me. I ran it for about 5 minutes the first time and adjusted the timing, the idle and added fluid to the tranny. Then buttoned her all up, put the breather back on it would try but not start. Took the breather off and it fired right off so I don't know. I don't want to run the engine too much as I only have headers for an exhaust system.
