68 Chevelle heat soak starter issue?

[1968chevelle327]

68 sat for many years, mechanically runs and drives well all things considered. Don’t know much about it but it has a 327 with mild cam, used to have a 750 double pumper that I swapped for a edelbrock 650, car runs much better.

One problem I’m having when the car gets to operating temp and I shut it off and try starting it a min later the car will barely crank. If I let it cool off for 20 min it starts right up.

In the morning when it’s cold it also starts right up?

Only think I can think is the headers are so close to the starter that it’s a heat soak thing?

Was thinking of trying to shield the starter from the headers?

Wrapping the closest header pipe might be easier to keep heat away ?
HD has this for $10. You can trim it with scissors.
I might do this on my cars too ; the header is very close.
You may want to check your negative ground cable to the block. Sand the contact point ; make sure it's good.

Good idea but what would be a good way to secure it to the starter or the header ?

I'd put it on the header, it'll also hold in heat so if it's on the starter it wont cool as fast

A couple of hose clamps on the header tube closest to the starter holding a double layer of blanket

The solution is simple..... wrap the headers, then install a heat shield around the starter. Problem solved. This isn't rocket science people.

Sounds good but the problem sounds like heat soak right?

Would you buy one of those wrap kits ?

That's what it sounds like..... too much heat, the windings in the starter become weak..... Buy whatever is easiest for you to install....

Yep, put it on, and then a heat shield.

This work ok as a shield?

No, get one that has a space between so the starter can breathe.... you don't want to keep the heat in, just block the heat from the header.

Chevy used a thin metal shroud, still available in reproduction today. Depends on your headers whether it'll fit. If you have 1/2 inch clearance, it'll likely fit.
I don't use chevy starters, I use the powermax minis, 9000 series, hitachi starters. They do the job very well, half the weight, 2/3 the size, and much more clearance for headers. Only issue is using them with points, you need to run a diode from your starter ignition wire on the starter, to your ignition. Simple wire mod.

You could have your headers coated if they aren't now.

Get a small gear reduction starter, it’s 1/2 the diameter of a factory starter giving more clearance Clarence.
