I'm in the planning stages of building a new drag radial car. Let me hear what you guys are running in your big block Chevy turbo combination. Stock or Aftermarket block, what block modification. Camshaft specs and explain why you went with that cam. Cylinder head mods such as special seats, valves or guides. What types of rings and gap? What is maximal boost levels can I run with a BB Chevy on alcohol? The vehicle will also be efi and twins turbos.
