Speedway Motors is the open wheel racing engine authority! Whether you have a 360, 410, USAC or Outlaw series Chevy race engine, Speedway has every part Sprint and Midget racers need. Our large assortment of cylinder heads, camshafts and racing valve train components allows you to tailor your engine for any racing condition. Speedway also has a variety of durable forged rotating assemblies, dry sump oiling systems and Dart engine blocks that can survive the rigors of open wheel racing. Race and win with Speedway Motors!
Speedway introduces forged rotating assemblies, with an optional balance job. Includes new 2-pc rear main seal crank, rods and pistons. Cranks are new so they use standard size bearings.
All Scat 4340 cranks are 2-piece rear main seal, internally balanced and weigh approximately 51-55 lbs. All balancing is done with our state-of-the-art Hines balancer by race mechanics with over 30 years of experience! A kit purchased with the optional balance job will ship in 24-48 hours. These rotating assembly engine rebuild kits may require additional charges for heavy metal.
If you are going to run this crank in a sprint car motor, you must have the crank flange turned down prior to balancing the crank to allow it to go through the motor plate.
Chevy 383: 4.000" bore x 3.75" stroke

If you only want to heat your water system then C&R’s NEW Portable Engine Heater is your answer. This totally portable unit utilizes a self-contained diesel fired heater to handle all of your pre-heating requirements. Its 12-volt design makes it entirely independent to an external power source, providing up to 4 hours of continuous operation on a full charge.
Once the unit is connected, it will gradually heat water in the race car to a temperature of approximately 200°F. The unit will then maintain this temperature until the unit is switched off and disconnected. This can be done manually with the on/off switch, or the 7-day timer can be programmed to start the unit at a desired time, providing you with a race car that is already up to temperature when you arrive at the track.
- Independent of generator power, can be used anywhere at anytime!
- One of the fastest engine heaters on the market
- Small size allows for easy storage
- Helps to move air from your cooling system
- “Smart” charger to optimize battery life
- Does not come with fill hoses.
Fabricated check valve recommended for quick connection, fill-ups & directional flow.
- Racesaver Sprint Series spec Brodix cylinder heads

Fel-Pro P1003 S/B Chevy 265-400 Steel Ring Head Gasket 4.166 Inch Borex
These Fel-Pro gaskets work with both cast iron and aluminum heads. Pre-flattened steel wire ring gaskets have the strength of steel wire sealing with minimum brinelling of aluminum heads. Pre-flattened copper wire ring gaskets will not brinell aluminum heads. They offer superior heat dissipation. Multi-layer steel gaskets offer current leading-edge technology and provide a long-term, leakproof seal called Perma Torque MLS.
- Gaskets are sold each
- Pre-flattened steel wire
- Nominal compression thickness: .041"
- Compressed volume: 9.1 cc
- 4.166" bore gaskets can be used on 400 race engines with up to 4.155" max bore with minimal chamfer
- When using aluminum heads, we recommend gaskets with soft copper wire rings (such as 344-1010). This ensures that the aluminum head is not "scarred" by the combustion seal. Shim style 344-1094 will also work well with aluminum heads.
