Big Block Chev Starter Heat Shield Gm no. 3943647

[PeteLeathersac]

Reminds me of that goofy extra support starter bracket that appeared on some Chevys around late '72...I hated that thing and always felt good tossing them too! .

My 69 Big Block has Hooker Headers. After engine is hot, when I shut down engine (say to buy fuel) starter will not work. Does anybody know if the above Paragon shield will FIT with headers ........and if in fact it helps prevent the problem??????

Thanks,

Chuck,

I was in the same boat as you with my 68. Wouldn't start after turning it off. I had to wait around 20 minutes or so before it would start again.

I bought the paragon shield, but it really didn't help that much. The original shielding is not for the starter, but for the solenoid, and most of the heat related problems stem from the starter itself. I ended up taking back several starters until I finally found one that would work when hot. I also have a 396 and Hooker Headers, so yes, it will fit if you decide to go that route.

A few suggestions I can pass along:

1. Don't have too much initial timing. This makes the starter have to push against a lot of compression and when the engine heats up, it's even more of a problem.

2. Use the shims that come with the starter. I found that just by adding or removing these, it really does make a difference. You may have to "play" before you get the right combination and it's not unusual to have to cut a shim in half for only one bolt hole.

3. Go with a name brand. I used an Auto ZOne remanufactured starter and had to go through several before I found one that would work when hot. Guys tell me that the NAPA starters are much better.

4. Better yet, go with a new "mini" starter unless you absolutely have to have original. These end the hot soak problems for good.

5. Go with the correct gauge battery cables or larger. Smaller gauge cables don't work very well.

6. Get the shortest cable you can for your application. Less resistance in short cables than long ones.

7. Not all batteries are alike. Cold Cranking Amps is not the same a Hot Cranking Amps and most batteries are rated at Cold Carnking Amps.

8. Keep all connections clean and tight.

Good luck

I bought one from the local GM dealer about 6 years ago for the 70 black 4spd car...turned out the original shield was still there and had slipped down somehow and I didn't see it can't remember if it was stainless or regular but I ended up using it on the 70 black th400 car and it fit fine. So...it wasn't all that long ago that you could stil buy them, and it wasn't much money.

I believe that the goofy starter braces appeared earlier than '72.

Ed has the handle on these confirming what my old mind seemed to remember. You could buy a 3954224 perhaps 6 years ago but not a 3943647. They are indeed corvette only shaped differently due to the vet exhaust manifold and will not fit the other BBC GM's.
19 years ago GM could not get me one and I paided dearly when I did find one.

Joe,

That SS shield for the Vetts's is only sheet metal. Wanna
bet I couldn't get it to look & fit like it belongs there?

I am the original owner of a 1969 Camaro 396 375hp. It came with a stainless steel starter shield different in shape than the Paragon Corvette shield. I had removed mine in 1969 when I installed headers. I have since removed the headers and used the original shield. Years ago GM released a galvanized shield that will fit but it is not the same as the original shield.

John,

I had heard that some Camaro's got the SS heat shield, but
by-and-large the majority of them got the galvanized one.

Still, I'd love to see image(s) of your shield; either
installed or off the engine. Just ho different is your
original SS shield from the others? Does it look like
the Corvette SS shield?
