The Avanti has a new battery, and starter......when cold spins over like crazy......when hot the car cranks at half the speed.....should I .............A. Wrap the starter with heat wrap, B. Wrap the exhaust pipe under the starter with header wrap, C. Wrap the fuel line leading to the carb.... D. None of the above? E. All of the above?

My first check would be to see that all the cables associated with the battery and the starter are in great shape with GOOD, CLEAN connections!
The engine's "loose" when it's cold and therefor easier to spin. Once it's hot and everything's tight, it's gonna be tougher to spin. Further, the R-series engines wore something beefier (in the way of a starter) than the standard V8s did just because of the higher compression. Are you sure you have that starter?[:I]

I would tend to think starter fix rather than insulate it. Protecting the fuel line may help with some vaporlocking.

Starter rebuilt last year......very little use since then....all cables new and tight....the starter is the correct Prestolite with four and not three coils.

And as I mentioned it spins like crazy when cold.

To clearify good connections....not only meaning the nut or nut-bolt is clean and tight...the wire is properly crimped and or soldered into the end fittings.

Also, the proper OR larger wire gage is used. A "1" or "0" cable isn't too big, unless you're a 100 point show car.

Also, that the system (the car) has proper and enough ground straps connecting all factory grounds at a minimum. Adding an engine to chassis ground or two will also help.
