906 or 915 mopar heads are better?
The choice between 906 and 915 Mopar heads largely depends on your specific performance goals and engine application. The 915 heads generally offer slightly better flow characteristics due to their larger intake and exhaust ports, making them more favorable for high-performance builds. However, the 906 heads are often praised for their durability and versatility, especially in street applications. Ultimately, the best choice will depend on your specific needs and the intended use of the engine.
Why do dogs angle their heads to hear better?
Dogs angle their heads when they don't quite hear a noise, or understand precisely what a noise means, in an attempt to hear it more thoroughly.
What GM engine had heads numbered 3817290?
The GM engine with heads numbered 3817290 is commonly associated with the 1969-1970 Chevrolet 396 cubic inch V8 engine, particularly the performance variants. These heads are known for their larger intake and exhaust ports, which contribute to improved airflow and performance. They are often sought after by enthusiasts restoring classic Chevys or building high-performance engines.
How can you replace fuel injector with carburetor?
Well, you have to replace the heads with a carbureted head, but why would you want to? Fuel injection is a much better system, especially if you're trying to modify an engine to get more power and better performance out of it.
Are the heads on a 65 289 motor reversible?
No, the heads on a Ford 289 motor are not reversible. The cylinder heads are designed to be installed in a specific orientation to match the intake and exhaust ports on the engine block. Reversing the heads would result in misalignment of the ports and poor engine performance.
Will 327 heads improve the HP of a 350 motor?
not really......you can have the 350 heads reworked for better performance. Besides, the 327 heads do not have the mounting holes for the alt. and other stuff that mounts to the front of the heads I tryed this on a race motor I built. The heads were just too small. ANSWER You can go to after market ex: Dart or whatever u want, have the cc you want for compression, valve size that u want ex: 202 intake, ported and polished. You will get top performance this way. Match the heads to the engine.
Can olds 307 7A heads fit on a 403?
No, Oldsmobile 307 7A heads cannot fit on a 403 engine. The Oldsmobile 307 engine has a smaller bore and different combustion chamber design compared to the 403 engine. Additionally, the 403 engine has larger cylinder bores and requires heads that are specifically designed for that engine to ensure proper fitment and performance. It is crucial to use compatible components when modifying or building an engine to avoid issues and ensure optimal performance.
When changing heads on a Chevy 350 what eles should be done?
What are your goals with the engine? Stock replacement, or increasing performance? How many miles are on the engine?
Can you use 305 heads on a 350?
Yes, you can use 305 heads on a 350 engine, but there are some considerations to keep in mind. The 305 heads have smaller combustion chambers, which can increase the compression ratio of the 350 engine, potentially leading to more power. However, this setup may also restrict airflow, limiting the engine's performance at higher RPMs. It's important to ensure compatibility with the intake manifold and other components for optimal performance.
Will 400 heads fit on a 350 motor and if so what will the difference be in the motor and power?
Yes, 400 heads can fit on a 350 motor, but modifications may be necessary for proper alignment and clearance. The primary difference will be in the engine's compression ratio and airflow characteristics; 400 heads typically have larger valves and ports, which can improve performance. However, the overall increase in power will depend on the specific head design, camshaft, and other engine components. Tuning may also be required to optimize the engine's performance with the new heads.
What size heads on 350 89 camaro?
Your question is a little vague, so im assuming you're asking which is better between 350 and 305 heads. Many people will tell you it doesnt matter. I think if you have a 350 engine then you should use 350 heads. the 305 heads will have higher compression, which will make the car louder, and somewhat faster, however, if you use 305 heads on a 350 engine then you should use a high octane fuel, so it will be better on your engine. Only use 305 heads if you know what your doing. if not you should probably stick with 350 heads. i hope that answered your question.
