What else can I help you with?
What is the combustion chamber size of heads with casting number 354434?
The chambers are 60cc. The heads are from 77-78 307 engine.
What size combustion chambers do Chevy L99 heads have?
Chevy L99 heads typically feature combustion chambers that are around 62cc in volume. These heads are designed for the L99 engine, which is a variant of the LS series engines used in various Chevrolet vehicles. The size of the combustion chamber plays a crucial role in determining the engine's compression ratio and overall performance characteristics.
Will heads off a 69 350 fit a 79 350?
Yes. Keep in mind that there were many different sizes of combustion chambers. If the new heads have smaller chambers, the compression ratio will be higher.
Will a 305 motor with 350 aluminum heads work?
no, small bore ,big combustion chamber you want big bore small chambers
How well does 400 heads work on 350?
Not that well. The valves are too small for high performance use, and the combustion chambers were too big.
Will Chevy 307 heads fit on a Chevy 305?
Yes, they will fit on the block. The larger combustion chambers of the 307 heads will probably reduce the compression ratio by a fair amount, reducing power output.
What can you do to a 68 chev 307 to give it more power?
Put 283 heads on it ,smaller combustion chambers mean more comprssion. hence more power.
What is 283 powerpack heads?
283 Powerpack heads have smaller combustion chambers, what gives a 9.25:1 compression ratio with flat top pistons. Powepack heads were always used with a ur barrel carburetor. It was an option that started with the 55-57 Chevys.
Where are the heads located on an engine?
On top of the driver and passenger silly! Just kidding. The heads are the block of metal bolted on top of the engine and contain the top of the combustion chambers. They may or may not also carry the intake and exhaust valves. Many aircraft engines and some racing engines have no heads, instead they have "pots" covering the piston and combustion chamber as one piece.
What is camel hump Chevy head?
62 up 327 300 hp and higher had "camel hump" heads. these have 64 cc combustion chambers for 10.5 compression on a 327.
Can you put 305 heads on a 350 bored 30 over?
Yes. Beware that 305 heads usually have smaller combustion chambers than a 350, which would increase the compression ratio, possibly requiring premium fuel to avoid pinging.
What the difference between 455 Pontiac heads and 400 Pontiac heads?
The primary difference between 455 Pontiac heads and 400 Pontiac heads lies in their design and specifications, which affect performance and compatibility. The 455 heads typically have larger combustion chambers, allowing for higher displacement and more airflow, which can enhance power output. In contrast, 400 heads generally have smaller chambers and different port configurations, which can influence compression ratios and torque characteristics. Additionally, the valve sizes and flow capabilities may vary, making them suitable for different performance builds.
