my 671 blown small block, makes dark blue smoke?

X2 on too high of fuel pressure at carbs......I ran a 142 blower with a edelbrock 800 carb....my fuel pressure was 7 psi...just my 2 cents

Thanks for the replies, I found out what the problem was , for future reference to the blower crowd.
the blower has seals behind the front plate, one of the seals was bad, I am assuming when it was rebuilt one of the seals got damaged, so when the blower would go into boost, it would suck oil in from the front blower plate. problem solved cool.gif
