    Glad to hear it. All of it except for the bell housing bolt. If GM/Chevy engineers deemed it un-necessary, go with their thoughts on the subject. The reason it wasn't drilled and tapped is because the water jacket is directly behind the unused bolt hole location. The 6.0 LSX blocks don't have them either and are rated at 1000 hp without problems. Do yourself a favor and leave it alone. Hope you get this message before tackling what could be a giant mistake.

    I appreciate the concern and I agree with your point, however, I did drill and tap it. I did not go as deep as the other holes however. I really don't plan on making an excessive amount of power. The process was successful. I did not drill into any water jacket.
    I hope to get some of my homework done and then I can tackle the engine install this weekend. I also hope to get my PSI harness as well. The final step is getting the new A/C components back in and charged.

    Engine is in!!! I just have to get the PSI harness installed. I think that I'm going to have to extend the harness for the O2 sensors (Using Schoenfeld Headers) as well as the harness for the MAF due to the aftermarket intake.
