grounds relocated?

[gjp]

Thinking today at work "why are the grounds on the block?"
They are sublect to heat, vibration and oil.
Why cant I put a ground block on the firewall like the 12v block and put all the grounds there? Just take a ground strap to the frame or something??
any reason why it wont work and has anyone done this?

Re: grounds relocated?

The big reason to have a ground on the engine is because of the alternator.
Another reason is because sensors like their own path to a guage or ECM.
