I would say the Speedo should work, the tach will NOT
As far as the faces, I have no clue.
The reason the tach will not is because the tach uses pulses from the distributor in order to determine RPM. Because a V6 has 3 pulses per every revolution, and a V8 has 4 pulses per revolution it would be off. Most aftermarket tachs will have a switch to accomidate for this.
