I don’t get it. With 190psi and 340 inches you should have a pretty nasty little small block. Torque (or lack there of) should not be a problem. What are the cam specs? And I agree with RRR that’s a lot of cranking cylinder pressure for 91 octane and cast iron heads. With 115psi it wouldn’t get out of its own way. Something seems odd.
