Summit® lightweight Nippondenso-type Protorque starters offer a 4.0:1 gear-reduction ratio and a whopping 1.9 HP. That's 222 ft.-lbs of racecar cranking power. If that's not enough, there are even more powerful 3.1 HP monsters, which are a pound lighter! They have a 4.44:1 reduction ratio and churn out an awesome 342 ft.-lbs. of torque. Both of these powerhouses are suitable for engines up to 502 c.i.d., and compression ratios of up to 18.0:1. GM versions are adjustable for five mounting positions; Ford types, for 18. A gold dichromate finish prevents corrosion and electrical shorts on both.

awesome starter

Summit RacingSummit Racing Verified Purchase

Great upgrade! Turns the motor over with ease & feels half the weight of stock stater. I would recommend to anyone shopping for a starter don't waste your money on a heavy/bulky stock one.

summit starter

Summit RacingSummit Racing Verified Purchase

very good starter, my chevy 350 turn very quickly over there is no problem with hot engine, more than enough room for my headers, the ability to turn the starter down make it very user friendly, only minor adaptation to the dust cover very happy with the purchase

Doesn't fit

Summit RacingSummit Racing Verified Purchase

Won't fit on a camaro with hooker headers..tried all three positions and it hits the pan or the headers or the block..bad design. Would work with zombie style headers but not street car headers.
