In some instances they are not drilled and tapped. You will find many connectors to disconnect: coolant hoses, transmission lines, engine accessories, vacuum lines, fuel lines, and the transmission. The Pontiac harmonic balancer generally bolted together through 1967, and this two-piece unit was introduced in 1964. The most numerous and common engines to get rebuilt are 350's 400's and 455's- all of which can be stroked to yield even greater displacements. Rare collector engines deserve professional rebuilds by shops.
By Rocky Rotella The traditional Pontiac V-8 engine's short block has some unique characteristics. The best two things to decide first are a be honest about cars real intended use and b engine budget. The engine mounts may be different for certain years, but most engine builders and restoration parts suppliers offer specific adapter kits for such situations.

Pontiac placed displacement callouts on each side of the block in 1968, and cast the last two digits of the displacement size into the center of the lifter valley. Step 6: Paint Engine Pontiac engines were painted many different shades of blue throughout the years. As stroke was added to increase displacement, main bearing diameter was increased to maintain sufficient crank pin overlap for adequate strength.

Cast pistons were used in essentially all production Pontiac V-8s, except for some of the unique maximum-performance engines. The bore size of the piston holes in the block and stroke crankshaft determine the cubic-inch displacement. But I still want to be able to enjoy the car. Rebuilding the 301 Turbo is difficult as hardly any parts are available. The basic Pontiac block is a robust piece of iron. I recommend replacing all hoses, mounts, and clamps now. Over the years, many different engines were slotted into the second-generation Pontiac F-Body.
Once you have accurately identified the engine, you should conduct a thorough inspection and then evaluate your ability to meet the requirements of the engine-building process. You cannot, however, let these codes be the sole determining factor as to whether you have the correct engine in your Firebird. This 1979 Trans Am engine compartment contains an optional L37 301-ciV-8. Depending upon the original application, there are slight differences in the length of the front snout, diameter of the rear flywheel register, and counterweight shapes. The 1970 and up Firebird engines received a different motor-mounting boss. I also suggest you find a piston manufacturer that is willing to custom build a set of pistons in advance for you.
Its wrist pin is offset slightly toward the thrust side of the piston, which is intended to lessen thrust load on the cylinder wall and provide quiet operation. Pontiac engine Pistons not available in std. Oiling System The oil pan is on the same plane as the crankshaft, and it contains a large sump at the rear. The date code and last two numbers of the year are near the distributor opening. Just fill out the or. A crankshaft of either type is quite durable and completely adequate for regular production engines and even high-performance applications. Some things are just worth paying for.
I pulled the heads and oil pan. Most kits are complete, call for parts in the kit. These features allow quick and easy determination of displacement. The key to removal and installation of your engine is patience and organization. Since the 326, 350, 389, and 400 share a 3. Color Matters Pontiac changed the color of the engines several times.

Numerous options are available for building an engine internally for performance enhancements, but that can still remain stock appearing from the outside. Most mechanically inclined car owners can competently rebuild an engine. Remove the transmission bellhousing bolts. Even a small part failure can have catastrophic consequences. The Pontiac V-8 uses a bolt-on oil filter adapter, and the type most hobbyists are familiar with comes in two distinct versions. The 403-ci Oldsmobile engines were slotted inside these cars also.
Most V-8 engines in Firebirds and Trans Ams spooled out a lot of torque so they were ideally set up for street driving. Step 2: Remove Linkage Disconnect throttle linkage, kick-down linkage if equipped , and shaker solenoid actuator if equipped. Less friction means more horsepower. Using an engine crane, attach a chain to the front eye on the water pump and to the rear of the intake manifold. Before you endeavor to rebuild your Pontiac engine, you need to honestly and accurately assess your mechanical ability, workshop space, and necessary tools.
