Is the standard HEI you converted to rebuilt,new or did you slap on one from a wrecker? Also what is the condition of the battery cables? Are they clean/tight at the starter? My car was having the same problem and i had the same thing happening in my fuel filter but it ended up being the batery cables.Just a thought.the whole time i was thinking fuel related.Then i ruled that out,when it wouldn't start/run hot or cold.
