I have the very nice ceramic coated 'doug's headers', -and a powermaster '3,5 HP' 'mini starter' -mind you, it's NOT for drag racing. -it's purely for street/strip..
-At first when cold, the starter cranked over the 11.5 compression engine like nothing....
-After driving on the highway, stop the engine, and start it right after again. -No problem..
Now,- the problem arises when the starters solenoid 'soaks' the heat from the headers..
-It simply won't start.. -You have to wait untill the solenoid cools down..
The solution is to override the starters solenoid, and locate a new solenoid to a cooler place.. -It was common on all the earlier fords, and if one needs a cheaper than 'painless wiring' solenoid -just order a ford starter solenoid..
-All the shelby race cars (you proberbly all have seen enginebay pictures of them) used them, -located on the passengers side ( in any cooler place)...
A starter can easily stand the heat from the headers, but the stock starters solenoid can not..
-So 30 bucks is cheap for a much better solenoid solution, compared to GM's original idea..
Hope this helps... -Helped my starting problems, if nothing else..
