And I have heard that aftermarket blocks get a hell a lot more hp than 5.

Well I'm about 60 short of Jerry so hopefully that new block will get me close. I hope Warren Johnson, or somebody of that caliber told you that. I should be in good shape then. Thanks for clearing that up. Good luck with your project
