Have the following questions:
What size pushrods do I need?
What size harmonic damper do I use?
What rear gears should I use?
Regarding torque converter, what stall speed should I use?
Regarding the timing chain, should I install the sprocket on the crank dot to dot, advance, or retard it?
What type/brand intake manifold should I use?

Any more info you can throw my way would be helpful. Not looking to street race the Camaro but would like to have some get up and go when needed.
