68 427 BB Mini Starter
I'm having hot start issues. This is what I have, new mini starter installed, new pos/neg battery cables, new alt, new batt.
I have headers and think the heat may be causing these issues. I do not have the stock bracket installed and have experienced some grinding on occasion. At this point I'm thiinking of going back to the original style starter so I can install the starter bracket and original heat shield. I thought I would come here to see how others with the same engine have avoided these issues while using a mini starter.

I'm assuming all wires and mounting surfaces are perfectly clean and in good condition.

What starter do you have? I've got a basic Summit mini based on a Nippondenso starter. It's been there for 10+ years and starts my 555" with 11.6 compression just fine regardless of how hot things are.

...your correct
Its the ground cable that's the problem....not the starter
the one under the Vette attached to the frame by the drivers seat....
Your OE starter is the one to use, those minis suck and a waste of money...Nor are those quick fixes the answer, heat shields, wraps and whatever.....If you would logically consider this, everything under the hood gets hot and the starters are not an exception......But what do I know, we only sell the best starters available any where.......and there factory stock just like the car {Vette} was initially delivered as new......but whatever.......

define your symptoms, " hot start issues" ??
does it click ? turn over slowly, turnover normal speed ?
without your actually symptom /problem everyone is just guessing.
a gear reduction starter, is all about leverage, making it easier to turn or crank the eng.
with better leverage/gear reduction your starter motor does not work as hard and draw as much current vs. normal starter,
espically helpful on higher compression motors.
do not use a starter blanket, they also keep the heat in the starter, a shield is good.
does the problem appears after sitting for longer than 10 minutes ?
or immediatly after shut off you have no start issues ?
if it is cranking normal and will not restart, you may be boiling your fuel away in the Hot Carb.
Corvette has 2 GND. cables, 1 from battery to frame, 1 from frame to Engine Block.
both must be in good condition.
for referance I am running a BB with gear reduction, and it works Great.
regaurdless of which you choose they must be installed properly, ... NO Grinding.
you have checked your starter Pinion clearance? .... when engaged ?
some grinding = a problem with installation, this needs to be fixed, need more details.
this could be causising or contributing to the problem.

While I still like the quietness of the Gm high torque starters they are just too big when you start adding larger tube headers..and friggin heavy
Had the same gear reduction starter thats 12 yrs old o 3 motors never given me an issue. Gear is finally starting to wear some thats ok it was a 100 buck swap meet special.

The starter just struggles and sometimes grinding is heard after the car has been running......almost like the battery is dead. Does the alternator charge through the starter? Also, can you send me a link on what starter you are using? After 10 minutes sometimes it will start but most of the time it will not.

again describe actual symptoms, does it turn over slowly, does it work correctly after complete cool down ?
The first thing you should do is inspect the flywheel teeth all the way around the flywheel,
next pull and inspect the starter pinion gear, then install properly, by verifying the pinion gap when the starter is in extended/engaged manually into the flywheel, adjust accordingly by adding shims if needed. sounds like the pinion gap is too tight to me.
making it difficult to turn flywheel and sometimes staying stuck or engauged after engine starts = grinding.
grinding is a loud and clear sign of improper installation.
this sounds more like an installation problem, vs Hot start problem.
you do have both Big GND cables correct ?
verify both gnd. cables and verify good flywheel teeth and pinion gap.
once this is done there should never be any grinding.
and no the alternater does not charge thru the starter.
the type of starter is irrelavant, the installation procedure is important.
If you simple bolt on a replacement starter, without verify pinion gap you can damage the flywheel,
I suspect your flywheel teeth will not look very good.
