hey gang hows everyone ? i have done some work on the engine 350 4bbl on my 84 fullsize silverado edition,new carb ,plugs ,wires,cap,rotor,filters all around. this engine is out of a 79 olds previous owner change god knows how many Ks on it but its alot. it runs good lots of power but i get that run on after the engines turned off. i know its carboned up good and ive been wanting to try seafoam on it but im concerned about loosening up the engine to much and everything rattleling. i will be putting it back to specs in the spring with the original 305 but i need it to last the winter so i can do my plowing. any ideas. thanks.

 

I would use the seafoam. It's not going to hurt anything.
