Old Newby - Thanks for the info. I saw the #, however I figured it couldn't be the casting number... isn't it supposed to be hidded at some secret location on the block, covered by a layer of grease making it virutally impossible to find.

Chevelle - I just rebuilt the carb, it was a (Holly reman) Rochester B, just like the one in the shop manual.
I bought the prebent line through americanclassic.com, however they are just resellers of the lines. The lines are actually shipped from inlinetube.com. My advice is to go straight to inlinetub.com if you plan to purchase any lines just incase you have any problems. I'm having problem returning the line because neither company wants to take responsibility for it and they keep telling me call the other company.

I'll check that casting number and post back with my findings. Thanks for the help.
