A Mini Starter with Maximum Punch

Your starter has the thankless job of turning over your engine no matter the circumstances. Whether it is hot or cold out, or your engine has lots of cubic inches or high compression, the starter in your muscle car or street rod has the tough task of spinning over your engine fast enough for the fuel and air mixture to be ignited by your ignition system. This takes roughly 400-500 rpms and if the starter cannot give you enough rpm you are not going anywhere. We all have heard that big block struggling to start at the end of the cruise night and if you don’t want to suffer the same embarrassing fate you need to upgrade your stock starter to a modern mini high-torque starter. The mini starter design uses the internal gear reduction to be able to provide higher rpm cranking no matter the operational conditions. Now you can crank that high-compression small block or big cube stroker big block without crossing your fingers when you twist your ignition key!

Ready to Handle Your Engine’s Cranking Needs

The benefits of utilizing a gear reduction starter are great. So much so that all the OE vehicle manufacturers have upgraded to similar high-performance starters beginning in the late 1990s. Chances are your daily driver uses just such a unit. They upgraded for the very same reasons you should—less weight, more room/access, and more starting power. Right off you can feel the weight difference. This Chevy high torque starter motor knocks nearly eight pounds off a large body stock-style starter. Remember being under a car and the starter getting heavier and heavier as you tried to hold it in place and start a mounting bolt? You will be thankful this gear reduction starter is easier to hold on to and weighs less! Cranking output is an amazing 180 ft/lb of torque thanks to the 1.4 kW motor with 3.7:1 gear reduction unit. The efficient mini starter motor combined with the gear reduction means your electrical system and battery does not have to work as hard to turn over your engine. The cast aluminum housing is strong, yet smaller and lighter than a traditional large body starter. We have designed this starter to fit most Chevy V8 and 90-degree V6 engines that use either a 153- or 168-tooth flywheel/flexplate. This includes small block V8 engines 1958 and newer and Chevy big blocks from 1965 and up. It will work with staggered-mount blocks that are common after 1976 by simply drilling and tapping the block casting hole that is already there to convert to a straight-mount configuration. So no matter if you need a SBC mini starter or BBC mini starter, this high torque starter has you covered.

Directly Replaces Your Weak Stock Starter

Installing our mini starter could not be easier. The starter is designed to not only directly replace your original starter but includes new mounting bolts as well. The billet mounting face is drilled to accept 153- and 168-tooth mounting spacing in the perpendicular (straight) mounting location and can clock the mini starter body in one of three positions for clearance. If your block uses the staggered mounting bolt pattern, you will simply drill out and tap an existing hole in your block casting to mount the starter perpendicular to your flywheel/flexplate. Due to the high torque starter small block Chevy mounting design, we include not only mounting shims to allow ring gear to starter pinion drive gear backlash adjustments, but starter nose housing shims to provide for the proper pinion gear to ring gear face clearance as well. The included shims and fully illustrated instructions mean no matter your combination you can shim our mini starter for a perfect, bind-free fit.

Faster, Easier starting is Just a Click or Call Away

Once you get our SBC high torque starter in your hands you will wonder why you did not upgrade sooner! With a clockable body to help clear chassis and exhaust fitment issues, a small form factor, and less weight, our mini starters are everything you need to get your project started without busting your project’s budget.
