[Darrin Christen]

Thanks for everyones help on this. The block does have the bolt holes that Ed mentioned for the bolt on cam plug, but it has 50mm roller brgs. I ordered the one Jegs had listed for the Dart blocks and it was identical to the one that is in my bowtie block. It was only $.87 cents from Jegs! Might be the cheapest thing in the motor! The plug measures 2.394" and the bore in the block measures 2.387" in case anyone is wondering.
