Pros or Cons of this product?, it is priced about $6.00 for 15 oz.

I was wondering if Sea Foam or another product on the market does the same thing just as good or better, on older Hi Performance carbureted engines?.

I'm not sure about carbureted engines, but for EFI setups Sea Foam is supposed to be just as good only cheaper.
This was a big debate among the Ls1 crowd, as it was GM's solution to piston slap.
From what I've seen though, the sea foam seems to work pretty good.
It is a bit messy, because you have to let it sit in the cylinders for a while, then flush it out.

We went through gallons of the stuff on the EFI motors when I worked on Cadillacs, and also some carbed cars.

We used the liquid, and would pour it down the throttle body while motor was at operating temp. It takes practice to get it in so it will work. I just pour it in at fast idle, just enough so as not to stall the motor, and when the can was just about empty, make it stall. (hopefully without hydro-locking it ) and the push it outside to soak overnight.

Why outside? Because smoke will roll upon start up!
Those cars don't normally get driven enough to keep clean on their own. On a peformance motor, I 'm not sure it would be needed.

It's amazing how good it works. I can only say to be sure to follow the directions on the can [img]graemlins/clonk.gif[/img]
