273 commando cam

Toolmanmike, I'm one of your fans. Your 273 build is admirable. I have not gone so far in my own build. All bearing surfaces etc were ok, so I chose not to grind the crank or bore the motor. Do you have opportunity to provide me feedback on my combo:
- D4B Edelbrock intake, 4 bbl dual plain
- Edelbrock 1406, 600 cfm intake
- Comp Cams cam part # 20-246-4, dur @ .015 270/270, 224/224 dur @ .050
- Electronic ignition
- Domed pistons, comp. ratio of 10.5:1
- Spitfire headers
Is good or not?
