Lightweight, strong and at a price you can afford. These 4340 forged steel cranks will really make a difference in your performance.
- Fits small block Chevy with 2-piece rear main seal
- Straight shot & chamfered oil holes
- Nitride hardened for superior wear resistance
- Profiled and pendulum cut counterweights
- Gun-drilled main line hole for lightening and equalization of crankcase pressure
- Star tail for reduced weight
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
NOTE: Piston rings are not included and must be purchased separately. Use Style C rings.
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
- Fully assembled
- Heads are certified serial numbered
- Ready and legal for use on a 305 c.i. Racesaver engine

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.
