Roughness Decelerating Through 4,000-3,000rpm

Post by opus10583 »

Hi,

1978 CS1, NOS short block, stock cams, '79-'80 CA electronic ignition (rebuilt, but for the vacuum capsule and springs) 10deg BTDC static, 32/36 DFEV, lightened flywheel, Al crank pulley, 40mi:

Engine feels rough dropping through the upper 3,XXX rev range?

Anyone have any ideas?

Thanks,
Mark
