Anybody have a gear reduction starter in their car? I would like to buy one for my LT1 because the stock one is just too sluggish and doesn't seem fit for a high performance car. Will any SBC gear reduction work, or are there specific ones made for the LT1? Thanks

I replaced my stock starter with a CVR "Pro-Torque" starter. More powerful than the stocker, and rotates to various positions, to help clear headers. I toasted two stock starters with header heat. That might be why your starter seems sluggish.... may be dying.

The CVR is a standard SBC starter, with dual mounting holes to allow it to fit witth either the 153 or 168-tooth flywheels. ScogginsDickey has it for $123 which is less than I paid for it 5 years ago.

It spins my 381 stroker over with no problems at all. I did have to grind a small corner off the mounting block to clear the lip of the oil pan.

Thanks for the help Injuneer. Which flexplate do I have, the 153 or 168 tooth? 153, right?? How about the 3 hp version, or would that be overkill?

Odd.... I don't know what the stock flex-plate is. My car was originally an M6, and was converted to the TH400 using a B&M SFI-rated flex-plate.

When I got the new CVR starter, I just used the pair of holes that lined it up with the correct clearance to the flex-plate.

I thought my starter was sounding "tired" because is was trying to turn over the stroker.... but the 381 is only 10.8:1, and the shop told me it probably took less torque to turn it over when it was a stock 350. It turned out the starter was burning out again, and drawing too much current, and sucking the voltage down to the point where the ECM had a hard time starting the engine. When I swapped in the CVR, it spun the engine really fast, and it started on the first touch of the key. The sound on the CVR is nice too.... smile.gif

How about this starter? Would I need an offset one?
