you can add a throttle body spacer, add a msd kit and platinum spark plugs and wires, cold air intake, you could gain about 15-20 more hp.
without swaping heads or getting head work done your looking at approximatly 400 hp depending on the cam and intake and carb match.
The maximum horsepower a 302 block can handle varies depending on factors such as the specific build and components used, but generally, a well-built 302 can reliably handle around 400 to 500 horsepower. Beyond this range, the risk of failure increases without significant upgrades to the internals, such as forged pistons and crankshafts. Proper tuning and cooling systems also play a crucial role in maximizing performance and longevity. Always consider the application and intended use when determining horsepower limits.
Impossible to answer without knowing the make, model, and year.
Seriously, don't mess with the cam that much unless you only plan to race it. Mild compression increase in the pistons and an RV cam will give you some decent improvement, and an exhaust header will also help.
A throttle body can be cleaned without removal. Several spray cleaners for throttle bodies are available at your local auto parts.
Yes, the pistonless rotary Wankel engine.
It will add horsepower for sure , and you will feel the difference if your a good driver and know your car well . The increase depends on the engine situation and the car model too, on v8's it will usually increase from 5 to 20 hp and you can hit the 20 easily if you reprogrammed your computer , without reprogramming the gains will be from 5-15.
Turns out the problem was never the throttle, it was an experimental in-line fuse that went out.
Advertised Horsepower is: 230 HP @ 3800 RPMs.
The horsepower refers to the measure of an engine's power without any loss caused by the gearbox or generator.
no *Correction - Reduced back pressure does usually result in more horsepower. Some cars run with resonators rather than mufflers which reduces the noise without as much back pressure, thereby increasing horsepower.
