Re: 350sbc pops and spits under load

Pull your spark plugs..

the end of the plug should be a white / Milk chocolate color if it's burning clean. If you have one pulg that looks different (black / wet / oily looking) then the gas going into that cyl is not being burned efficiently. Could mean the plug is fouled out .. and $2 replacement would fix it .. It could also mean other problems such as a burned valve, maybe broken valve spring, .. etc. But, check the simple stuff first before you pull the heads.

.. just my .02.
