How to Build a Funny Car Engine

Funny cars are drag racing vehicles that are designed to accelerate as quickly as possible over a quarter-mile course. The engines in these cars are some of the most powerful in the world, and they require a great deal of precision and expertise to build. In this article, we will discuss the basic steps involved in building a funny car engine.

1. Selecting the Right Parts

The first step in building a funny car engine is to select the right parts. This includes choosing the correct block, heads, camshaft, intake manifold, and carburetor. The parts you choose will depend on the specific type of engine you are building, as well as your budget. It is important to do your research and choose parts that are compatible with each other and will meet your performance goals.

2. Machining the Block and Heads

Once you have selected the parts for your engine, the next step is to machine the block and heads. This involves boring and honing the cylinders, decking the block, and porting and polishing the heads. These machining processes are critical to ensuring that the engine will perform properly and produce maximum power.

3. Assembling the Engine

Once the block and heads have been machined, you can begin assembling the engine. This involves installing the crankshaft, pistons, connecting rods, camshaft, intake manifold, and carburetor. It is important to follow the assembly instructions carefully and torque all of the bolts to the correct specifications. Once the engine is assembled, you can install it in your funny car and begin tuning it for maximum performance.

4. Tuning the Engine

Tuning a funny car engine is a complex process that requires specialized knowledge and experience. The goal of tuning is to optimize the engine’s performance by adjusting the timing, fuel mixture, and other factors. This process can be time-consuming, but it is essential for getting the most out of your engine and achieving your racing goals.

5. Maintenance and Care

Once your funny car engine is built and tuned, it is important to maintain it properly to ensure that it continues to perform at its best. This includes regular oil changes, filter changes, and inspections. It is also important to store the engine in a dry, climate-controlled environment when not in use. By following these maintenance tips, you can help extend the life of your engine and keep it running strong for many years to come.

Conclusion

Building a funny car engine is a challenging but rewarding experience. By following the steps outlined in this article, you can increase your chances of success and build an engine that will power you to victory on the drag strip.
