i put in a whole bottle of that nos octane boost for SUVs in my 94 cougar's 351W. i did this because she was knocking and pinging due to the removal of my smog pump. the problem is she only had a 1/4 tank. i did not fill her up with gas. could this be a reason why she wont start good?
 
that loud sound was from my leaking exhaust manifold. i figure maybe if i change my carb mounting gaskets i should be good. i removed the carb for awhile and reused the old gaskets
 
From what I've heard, the octane boost stuff will only give you something like a .1 or .2 increase in octane.

From what I've read, deleting the smog pump shouldn't affect how the motor runs. It looks like you need to plug the holes with a bolt on the back of the heads?? where the tubing of the smog pump system go into.

Pleny of info on that on the net.
