High Torque Starter

[Golf Caddy]

I have been experiencing "vapor lock" with my 68 Deville with the 472 motor.  A little background, during restoration, motor was bored out 30 over and we put a new cam in.  Now when car has been driven and shut off, very difficult to get it to turn over and start.  Checked timing and all is good.  Is there a high torque starter available that would solve this problem.

Thanks,

The common heavy duty solenoid spring should be available. You can combine this with a heat shield for the solenoid.
Heat soak is your culprit here. (assuming your starter is within spec.)

What helped me was 0 gauge battery cables.

How about the condition of the starter?   My 73 would sometimes do that on and off over the last 10 or so years till it would not start at all.   Took it apart and the brushes were pretty much gone.  I never suspected them being worn because when it was cold it seemed to spin just fine. 

Old and poor quality new cables are also a common problem so don't overlook those.

If you are sure all you need is more power then here you go.....

I believe this topic has been brought up more than enough to create a "stickey" on it.  If you have a stock motor, u[ to 10:1 compression AND if all the cables and their connections are good, the standard Cadillac starter is more than adequate. That said, over the years, the replacement starters sold have actually been essentially Chevy starters, and what is listed in the catalogs such as Rock Auto and others as a "high torque" starter is the correct starter for a Cadillac.  The difference is about an inch or so in additional length to the armature and field coils (by way of a longer housing). This adds the correct amount of surface area to generate he required torque.

Hearing that there was an engine rebuild reminds me of another possibility to be looking for. Ground straps are sometimes forgotten (engine to body) or (engine to frame). Make sure the main battery cable goes where it is supposed to be, be it straight to starter or to frame, depending on car.       Joe Gibeault

Tom,
  I'm with Greg....the stock starter (if it's the right one) should be more then adequate for cranking the motor. I once had a Lincoln 460 high compression motor and it simply didn't want to crank when hot. Batteries, cables, starter were changed over and over again. Turn out, "rebuilt" starters from shops were all generic and pretty much interchangeable. The CORRECT starter had heavy duty windings in it for my application. So, talk to your friendly starter overhaul shop and install the correct starter......walt...tulsa,ok
