Putting a few things back together and I can't find my SBC book so I'm going with the Toyota torque specs on a few items. Does this sound right for a 350 as well?

Oil Pan: 7 ft lbs
Flywheel: 47 ft lbs

Oh and...

Clutch Pressure plate: 14 ft lbs
Bell Housing: 47 ft lbs

Thanks

On a SBC with Vortec heads, the intake manifold uses a special gasket and only gets torqued to 11psi or some number that seems too low. Torque it to a higher spec and the intake will crack................don't ask me how I Know
