340 Power on the track

We added more gear, more convertor, i did a basic gasket match on the ports, work on the exhaust more than the intake, 2.055 intake valve. the intake manifold was tuned up, cam is a Bullet .560 lift not real big. same KB pistons from 2009 with good Total Seal rings. Worked on the getting the combo right more than anything, if you just throw parts at it, does not always come out well.
Yes, it's the symbiotic relationship of the parts, as someone in California might say. Lol... Well done !!
