340 Stroker Build Need LOTS of Advice

For 91 pump gas it's safe to be around 9.5-10 to 1 compression. That's a 20cc-18cc dish with a 4" stroke and "65cc" heads (67cc measured). Cam doesn't seem like it's going to be that big to bleed off compression.

• Scat balanced rotating assembly forged or cast. Cast will take 525-550 hp.
• RPM dual plane or Air Gap dual plane intake
• 750 double pump
• 240-250 deg @0.050, .500-.550" lift cam ballpark range.
• Edelbrock springs IIRC are good to .550" lift
• TTI or Thorely stepped headers.
