Check the timing then do a compression test.  A V8 will happily idle on 6 cylinders or with numberous faults that only show up under load.

Check the mixture as it may be running too lean.

hi mate make sure theres oil in the dash pots on top of the carbs as this can cause over fueling and popping back :wink:
