    I have a 78 chev with a 350. I just put on an eldebrock intake and eldebrock carb. I realy have to crank the engine over for about 10 minutes before it will start. Then it run fine.
    Before I put the intake and carb on the truck it had a 2 barrel carb and it started the same way. I just figured it was the carb causing the problem.

    I have put in an off road needle and seats into my elebrock carb as well. I am going to check the timing tomorrow to see if that helps and maybe some new plug wires.
    Could this hard starting just be timing?
    Thanks alot
    Matt

    My vote is for the timing. Maybe the timing chain is stretched too....

    how does it run once it does start...does it blow black smoke out like there's a lot of fuel being burned up? sounds like it could be timing, or a worn pushrod for the fuel pump...

    I haven't been able to check my timing yet (I forgot to borrow one from the father in law).
    There is not choke set up right now. I did notice the my clear feul filter was pretty much empty and after I cranked it over it filled up slightly and then started after a while. Then all day long the filter has stayed right full and the truck starts now problem.
    Is it normal for the fuel filter to empty like that?
