High compression starter
High compression starter What starters are you guys using? I've been running an LT4 starter but the Duralast ones just don't seem to last. They arent breaking but they arent on the car long before i have to start hitting them with a hammer. Running 11.4CR in a 396
Stock starter here with a 235 Psi cold cranking 383 with a zero gauge wire and battery located in the rear. Correct me if I'm wrong but the factory starter is already a good gear reduction starter.
Yes the LT4 got a super special magical piece, but that doesn't mean we should be asking a starter to crank over even more compression than stock LT4 with 20 year old undersized battery cables.
The point we were trying to make was that even the lowly POS LT1 junk can do the trick if you give it a proper power supply.
I agree with the poster that suggested the OP is likely causing the LT4 starter damage with small stock cables.

OP
as mentioned a heavier gauge quality battery cable & grounds if you still have original cables would be recommended. Innovative Wiring is one source for a quality set

FWIW the LT4 aka "Vette" starter from autozone is a OSGR (Off Set Gear Reduction) type.
The LT1 starter is a PMGR (Permanent Magnet Gear Reduction) type

Verdad Gallardo I guess that brings me to another question. While I'm at it, I might as well go ahead and relocate the battery to the trunk. Is there a kit out there that yall have used that worked good or did yall just have to piece something together?
No kit will work well IMO.
Buy the box, and cutoff switch then wire it all up with quality stuff. I have 1/0 from switch to starter and 1/0 from alternator to battery, then a block to chassis 1/0 and a battery ground to chassis 1/0.
Its gonna be a pretty penny when done correct.

I've put about 3 of those on there. They all do the same thing. they work great for a little while. Then it stops turning until i hit it with a hammer. I'm convinced its the battery cables

Yeah - all that with the cable hygiene, and don't forget there are tables in the pcm for you to retard the timing when cranking the engine - maybe a little less timing would help you a bit. Also, if it is a warm start problem due to headers, get some heat shielding on there. When/if you do battery in the trunk, consider running the ground cable all the way up front - while it is not entirely necessary and adds a little weight, your old steel frame might not be such a wonderful conductor as a new copper cable when several hundred amps needs to get through, and each connection usually introduces another voltage drop.
There are several decent battery re-location kits on the market:

The 93 base vette has an offset gear reduction starter. From what I understand it fits 92-96 vettes. I think NAPA can get a new one for about $150
Is that the kit you used? I like how the ends are already put on but are they the right length?

It's moving more in the direction of a street/strip car. plus i want to use that space for a nitrous fuel cell in the future. I may just get lazy and just replace the factory cables.
