Just put in a 360 LA engine in my 69 Swinger. I hooked everything up went to turn it over. It turns over but not starting. I replaced the fuel pump because I took the fuel line off of the pump and it was bone dry. Put the fuel line back on still nothing. Put some gas directly in the Edelbrock 1407 carb and it just spit it back out when I turned it over. After several attempts of trying to turn it over I notice an almost hissing sound. Could this be a vacuum leak? That's where I'm at with this. I don'rt want to start doing 15 different things at once. I just want somewhere to start. Also I notice that the ground strap that I have mounted from my firewall to my valve cover is warm while cranking.
