Starter turns slow when hot

My starter is not high torque so it turns slowly when hot, even after I've been parked for 2-3 hours. But the next day is turns normally and I think it's time to change it. I haven't the slightest idea what brand is it. All I know is that the solenoid is mounted on the bottom of this starter so a friend of mine told me that is a wierd one. My motor is a 454 LS6, 11:1 compression, and a high lift hydraulic cam. I'm looking for a high torque starter with the solenoid mounted on the bottom. Can anyone give me some tips on name brands with this application?

Never saw a Chevy starter with the solenoid mounted on the bottom.......

You may need a starter, but it also could be the heat from the headers....a heat shield between the starter and exhaust may help......A lot of people also put on a remote solenoid (Ford type)

Thank you for your feedback. I think in my case since I live in Hawaii I should seek locally. That way if I run into problems with the fitting and clearance, I can return it without shipping charges. And yes, the headers are near the starter and I will definitely install a heat shield around the new starter.

Not sure if the LS6 has the same bolt pattern as a Mark IV big block. But I used a starter for a 2000 S10 pick up truck. High torque mini starter.

Good idea, but invest in a QUALITY mini starter. Some of the offshore mini starters available at auto parts stores will not give good results. One of the issues is that the bendix will not dis-engage as soon as the engine starts and drags a bit. Look for a genuine AC Delco starter and you may be alright.

you may want to install a remote starter solenoid kit, if drag is a big player in your application then the kit would kick the starter off at 1000rpm and kick it on if the rpm drop below 600, but that's just the basic kit, you can have then higher or lower depending on what you'r idle is, and yes, a shield would be best if it's getting to hot.

Once again, thanks gentlemen. That's exactly what I'm leaning on; a mini high torque starter. In my past history, I had a 454 mounted in a 92 chevy truck and I used the Tilton mini starter. It worked great but that starter was costly (almost $400). If anyone out there has a 454 with a mini starter, please give me the brand name so I can narrow my search. At the same time I'll jack-up my car to take a snapshot of my starter so I can take it to the auto parts store to give them an idea on what I'm seeking. Thanks.

I would suggest you do a voltage drop test on the wiring to and from the starter. This is a web page on how to do voltage drop tests, it is a little bit of a long read, but very informative:

Replaced starter

Just wanted to thank all of you for your input and sorry for the lateness in posting the results. I replaced the starter (MSD high torque) and battery (Sears Platinum Die-Hard). It starts fine now and the starter is not located near the headers like the previous one did.
