Build suggestions for 340?

AJ, typical high compression 340’s typically dyno’d over 300 hp. Adding a 750 carb, headers, well ports heads (2/02-1/60) w/a cam like a Comp or Lunati 268 has brought the goods of 400+ hp home.

The heads we had ported flowed in the 250/255 range.
Similar to the Edelbrock head flow curve.

Later we added more aggressive ramp (& lift) cam of approximately the same advertised duration which added 30 hp. The quicker valve lifting action with a bit more duration @.200 it was still a nice street camshaft.
