Just installed a new flat tappet cam and new lifters. We set a timing with timing light. The engine turns nicely but it won´t start. I checked for the spark and it turned out to be ok but the plugs were wet. Sometimes it poped to the carb sometimes it banged to exhaust.
It`s a carbed engine with 600 cfm edelbrock carb and blue holley fuel pump. The fuel pressure is about 6psi...
Thanks

 

Distributor is 180 degrees off

 

i checked it and it wasn´t....

 

If you installed your timing chain set at dot to dot alignment, but installed your distributor pointing to the #1 cylinder and set it up as such, then yes, you are 180° off. At dot to dot alignment, the #6 cylinder should be recieving spark.

 

That's what that all say....

Until they turn it 180 degrees and the car starts.

 

Yes, that´s exactly what we did. I´ll try to turn it.
But is there also a possibility that the valves are set wrong?? We installed new anti pump-up lifters and i´m not sure if the valve lash is correct. ..

 

Zero-lash them, and final-adjust them after you get the car running. THen they won't matter.

 

Thanks for the fast replies. I´ll go and try my luck

 

Well the same problem continued although i double checked everything. Finally i screwed on 750 speed demon and it cranked!! This carb looks brutal on a small 305, but it must run with it until i´ll get my 600 refreshed.
