The other big mystery is how we ended up having this discussion on 67Hat34c's thread about SeaFoam and ATF in gas engines. Anybody have any solutions to that??? Miguel???

I would NEVER repeat NEVER pour ATF down the carb. I did this on a 327 '63 Biscayne and it freed all the carbon BEHIND the rings and she smoked all the way to the bone yard. The carbon is necessary to seal the .001" ring land clearance. ws
