I believe i know what you are talking about on the j-tubes, but its a street avenger carb which is aftermarket so im sure there aren't any j-tubes though i havn't looked. My dad is thoroughly convinced that the engine came out of a dump truck and is a piece of crap that gets 4mpg and was beat up. did GM EVER put marine stamped engines in trucks??

I guess anything is possible. Maybe the factory needed an engine that day and were low on car engines, so a marine engine was pulled to do the job. If it is either a truck or marine engine the cam grind will be more toward the torquey side as opposed to high rpms. That would be one major difference I forgot about.
