Welcome Jed glad to have another Texan here. I grew up in Austin and retired to Hamilton, Tx (think intersection of Hwy 281 and Hwy 36. Like Randy, spent many, many hours at the old Alamo Dragway. If you need mechine work done when you get a engine, I have someone I have used for over 30 years on 348/409s in Austin. Randy (Austin Bubbletop) uses him also. Good luck on your build.
