    High Torque Mini-Starter
  • Small Block/Big Block Chevy & 90° V6
  • 1.4KW 12V Motor
  • 11:1 Maximum Recommended Compression Ratio
  • Fits 153 & 168 Tooth Flywheel/Flexplate

    High-torque, gear-reduction design. 100% NEW, not rebuilt. Offset design results in more clearance between the oil pan and the starter, and can be rotated for additional chassis clearance. The high-torque, high-output motor spins the engine over faster than stock starters, delivering 40-50% more cranking power. 3.75-to-1 sealed gear-reduction drive and full ball bearing construction. Includes shims to set pinion-gear engagement (when necessary). Approved by all leading sanctioning organizations.

    Fits all Chevy 90° V6, small block and big block V8 engines using 153 or 168 tooth flywheels. Heavy-duty PROFORM P/N 778-66258 weighs 1-1/2 lbs. more and is 1' longer than P/N 778-66256.

Small Size, Big Power! This 100% new mini-starter is the hot ticket for applications where tight header clearance tends to make your starter hot. And since it's only 2/3 the size of a stock starter, it will fit where a stocker won't. Choose from standard 1.4 kilovolt or hi-output 2.0 kilovolt model, with no increase in size.
