My pontiac didn't come from the factory with long headers, and 500+ hp.. -And not so much room for stock (if any room) starters.
-So the design to deal with too much heat for the solenoid, was -as fords- a remote starter.

-It came with cast iron exhaust manifolds (not very long compared to headers). -that's why the solenoid wasn't as exposed to heat.

-Fords had smaller engine bays, -not so much room for big starters.

-As Vikki said, heavy duty starters were available.

Not to mention (as we can see from Thomas' pictures) todays headers almost rely on 'mini' starters in order to fit.

I'm sure you don't hate Fords.. -why should anyone of us in here hate a company that introduced the 'ponycar' concept..

-Who knows.. -without the mustangs, -maybe no firebirds/camaros.

-But there is really no need to debate what design came originally, or first.

-Original designs were compromised in relations to what was easiest to fit and cheapest for any of the carmakers..

-Only if they had no other choice the design would be best quality available. (just like today).

I have 12 bolt posi, from moser, and recommend it.
-However the only reason why I didn't go with 9 inch, was heavier weight.
-Yeah I got rid of the chrome cover too (LOL), and put on an aluminium.(which I eventually painted black)
