How did s and s make the Sidewinder engine?
S&S did the engineering ahead of time. Like all of the other products we offered, we supplied everything needed in a nice, neat kit including detailed instructions on how to modify the stock crankcases and assemble the engine. What this meant was that any competent engine shop could build big inch Harley big twin engines at an affordable price.
Why do we call our big bore cylinders Sidewinder kits?
The story of the S&S® Sidewinder® cylinders & kits. The story of the S&S® Sidewinder® cylinders & kits. Every now and then someone asks me why we call our big bore cylinders Sidewinder® Kits . The naming of that product was one of those things that just sort of happened. An idea or a circumstance occurs and it just sticks.
What’s the best speed a sidewinder can go?
To prove the point, we took them to the Bonneville Salt Flats complete in street trim running the same parts we were selling to shops and recorded a best run of over 145 mph with our 98” 1977 FX Lowrider. That same motorcycle was used testing cams at a local drag strip and made 45+ runs on one occasion.
When did the Sidewinder for Shovelheads come out?
An idea or a circumstance occurs and it just sticks. My father introduced Sidewinders for Shovelheads back in 1978, shortly after the United States bicentennial celebration in 1976. With that in the back of our minds, we were thinking of the Gadsden flag of the original 13 colonies.
Do you need a longer rod for a stroker engine?
For example, pistons for a longer stroke can require a longer rod just to allow the piston to clear the counterweights when the piston moves to bottom dead center. Stroking an LS engine is even more critical. GM shortened the length of the barrel or cylinder sleeves on all the Gen III and IV engines.
What’s the minimum clearance for a stroker engine?
Building any engine means checking everything – including the deck height clearance between the piston at TDC and the block deck. For engines with steel rods, the minimum piston-to-head clearance is 0.040-inch but lots of builders push this to 0.035 or less – but that only works with minimal piston rock.
What makes a Chevy Stroker a stroker engine?
The original 400 small-block and 454 big-block Chevys were both displacement escalations of earlier engines and their longer strokes required the expedient move to external offset balance weight. These are identified by the additional weights added to the harmonic balancer and flywheel/flexplate.
How tall is the block on a Chevy stroker engine?
A quick deck clearance calculation for any piston and rod combo is block deck height – ½ stroke – piston compression height – rod length. So with a small-block deck height of 9.025, if we have a stroke of 4.00 inches, a compression height of 1.150 inches, and a rod length of 5.850 inches then: (4.00 /2) + 1.150 + 5.850 = 9.00 inches.
