There are a few different ways that you can identify 283 power pack heads. One way is to look for the casting number which should be located on the back of the head near the exhaust port. Another way is to measure the intake and exhaust ports; they should be 1.72” x 2.125”.
Finally, you can also identify these heads by their unique spark plug angle of 45 degrees.
- Locate the power pack head on the power pack
- The power pack head is a small, black box with two wires coming out of it
- Follow the wires from the power pack head to the solenoid valves
- The solenoid valves are larger black boxes with wires coming out of them
- Trace the wires from the solenoid valves back to the control panel
- The control panel is a large box with buttons and switches on it
- Find the model number on the control panel
- The model number will be printed on a label somewhere on the control panel
Power Pack Heads Vs Camel Hump
When it comes to heads for your engine, there are two main types: Power Pack Heads and Camel Hump Heads. Both have their own set of pros and cons that need to be considered before you make a decision on which one is right for your engine. Here’s a breakdown of each type of head, so you can decide which one is best for your needs.
Power Pack Heads
Power Pack heads are designed for maximum airflow and performance. They feature larger intake and exhaust ports than Camel Hump heads, as well as bigger valves.
This allows them to flow more air, which results in more power. Power Pack heads also tend to be lighter than Camel Hump heads, which can save you some weight.
The downside to Power Pack heads is that they can be more finicky than Camel Hump heads.
They require more frequent maintenance and adjustment, and they’re not as durable as Camel Hump heads. But if you’re looking for maximum power from your engine, Power Pack heads are the way to go.

How Do I Know What Gm Heads I Have?
There are a few ways to determine what GM heads you have. The most accurate way would be to remove the heads and take them to a machine shop that specializes in cylinder head identification. They will be able to tell you for sure what heads you have based on the casting numbers.
Another way to try and determine what GM heads you have is by looking at the stamped code on the driver’s side of the cylinder head, just below the valve cover rail. This code will give you the date that the engine was assembled, as well as an abbreviation for which plant assembled it. The three plants that built GM engines were Flint, Michigan; Tonawanda, New York; and St.Catharines, Ontario Canada.
The first letter of the code corresponds with the month (A=January, B=February, C=March, etc.), while the second letter corresponds with the year (9=1969, 0=1970, 1=1971, etc.). So a “CA” stamp would indicate that your engine was built in March of 1970 at either Flint or Tonawanda. A “DO” stamp indicates July 1971 at St.Catharines .
How Much Horsepower Did a 283 Engine Have?
The 283 engine was introduced in 1957 as a high-performance option for the Chevy Bel Air. It was available in two versions: a base model with 185 horsepower and a fuel-injected version that produced 220 horsepower. The 283 became one of the most popular engines of its era, thanks to its combination of power and affordability.
In 1963, Chevy introduced a revised version of the 283 that featured an increased bore size and new cylinder heads. This resulted in a power increase to 200 horsepower for the base model and 250 horsepower for the fuel-injected version.
How Do I Know If My Chevy Has Double Hump Heads?
If you’re not sure whether or not your Chevy has double hump heads, there are a few ways to check.
First, you can look for the casting number on the heads themselves. The casting number will be located on the side of the head, near the valve cover.
If the casting number starts with “381” or “396”, then you have double hump heads.
Another way to tell is by looking at the spark plugs. If your Chevy has double hump heads, the spark plugs will sit at an angle, rather than being perpendicular to the head.
Finally, you can remove one of the rocker arms and look at how it’s mounted. On a head with double humps, there will be two screws holding down each rocker arm. If there’s only one screw per rocker arm, then you don’t have double hump heads.
Where are the Casting Numbers on Chevy Heads?
If you’re looking for the casting numbers on Chevy heads, they can be found in a few different places. First, check under the valve cover – there should be a raised boss or pad that has the casting number stamped into it. If the valve cover has been replaced, you can also find the casting number on the top of the head, just behind the rocker arm studs.
Another place to look is on the side of the head near the exhaust ports. There may be a small tab with the casting number stamped into it – this is called an “exhaust identification boss.” Finally, if you remove one of the spark plugs, you can sometimes see part of the casting number through the hole.
Keep in mind that not all Chevy heads will have all of these identifying marks – some will have just one or two. But with a little patience and perseverance, you should be able to track down those elusive casting numbers!

Conclusion
If you are looking to identify a 283 power pack head, there are a few things that you can look for. First, the heads will have the letters “PP” stamped on them. Additionally, the heads will have smaller combustion chambers than other heads, and they will also have thicker casting around the valves.
Finally, the exhaust ports on these heads will be larger than those on other heads.
