Wow! Look at that Power and Torque. Surprised it runs like that with the RPM intake.
Was the manifold ported and what size carb? Is this a 4.125 Dart block?
I'm building a 427 also,but using the 225 TFS Highport heads.
Maybe I don't need the recommended Super Victor intake!
No,it's not a Cobra,but the engine tech here is excellent!!!!
I do have a question on your dyno graph. Why is the engine going so lean at the top of the run?
