Id go T-Ram, big motor with loads of torque and a huge carb? Hood clearance a non issue? Lots of test prove the T-ram isnt the low RPM dog that they used to be known for.
Spot on ! A 493 needs big heads ,big camshaft, ..That requires big gears ,a tight 3000 plus stall converter, then those long runner lengths , start to viberate VELOCITY.
Just ,personal knowledge....
