Hey all, I have a 92 Z28 with a built up Miniram'ed 383 with shorty headers and a LT1 starter. Im wondering what you guys suggest for a insulator on my starter? Should I go with a heat shield, or wrap the starter with some reflective Mylar? Thanks in advance.

 

heat shield will be fine.

 

Just finished fixing my hot start problem. Used both the Thermotec Wrap and also a Mr Gasket heat shield. Replaced the starter with a new reman.

Funny, a starter motor for a 1969 Chevelle 350 was $119(can) yet a heavy duty starter for a 1969 427ci Bigblock Corvette was only $89 (can)

Took the BBC starter and just swapped nose cones.

Seems to start fine now. required a few mods with a crow bar to ensure there was a "Air Gap" between the heat shield and header tubes. They are very close to the starter.
The positive starter cable was also corroded for sitting all winter.

You can check your starter cable for resistance by reading the voltage off the starter solenoid to ground with a volt meter, while cranking over the starter. Should be 9.5V or better.

 

I'd spend the 15$ just to be sure. Alot of guys will probably comment on how heat sink in starters is a myth, but I believe it seeing as that I had a starter a year ago that wouldnt budge after driving in hot weather, but after you cooled down 30 minutes later, it kicked right over...like clockwork.

Either way, you'd only end up paying 15$ for an AC Delco one, but I'd rather not have to keep replacing them.

 

the shield that goes around the selinoid is all I use and I use a stock autozone starter and headers

I have not had one problem with startups

 

GuitarJunki17, spend $15 on what? Im not sure what your talking about. Thanks.

 

How about ceramic coating? Just a thought.
