A WALKTHROUGH OF A JEEP ENGINE BEING BUILT AT GOLEN ENGINE

Machining and Pre-Assembly
Cleaning Process

Cleaning Process


We start off with a bare greasy block and put it into our electric oven where it bakes at 800 degrees for 5 hours. Once it comes out of the oven all the grease is turned to ash and it is ready for the blasting process. Our shot blaster shoots stainless steel shot at the block for 45 mins to get the cast iron back to new form.

Cylinder Boring

Cylinder Boring

We bore our blocks oversize using our Rottler bore mill.

Block Decking

Block Decking

Decking not only gives the block the proper surface finish to seal the head gasket but it also allows us to tighten the quench height.

Cylinder Honing

Cylinder Honing

Our new Sunnen SV-15 Hone keeps cylinders straight and perfectly round.

Line Honing

Line Honing

By line honing the blocks mainline we can blueprint the main bearing oil clearance to a perfect .002”.

Crankshaft Balancing

Crankshaft Balancing

We dynamically balance each crankshaft in our Hines Balancing machine for smooth engine operation and long life.

Connecting Rod Sizing

Connecting Rod Sizing

By honing the rod big and small ends we can blueprint the oil clearance and keep the housing bores straight and round.

Measuring Clearance

Measuring Clearance

We double check all housing bores to ensure they are all identical for proper bearing clearance

Seat and Guide Work

Seat and Guide Work

Our Sunnen VGS-20 seat and guide machine uses carbide cutters to lay in a perfect three angle performance valve job, this machine uses a pilot system to keep the valve job concentric to the valve guide.

Valve Cover Machining

Valve Cover Machining

We mill our aluminum valve cover so it is ready for our Golen Engine 4.6L Stroker Sticker.

Engine Assembly and Dyno Tuning
Jeep rotating assembly

Jeep Rotating Assembly


Jeep rotating assembly all balanced and ready to install. We take the extra time to polish the crank and check all journals for proper size.

Pistons & Rods

Pistons & Rods

Sealed Power Hypereutectic pistons and Aftermarket Forged Steel connecting rods ready for installation. The new forged rods are a nice upgrade over the factory cast versions.

Machined Block

Machined Block

Here is our fully machined block all washed and ready for all the new parts.

Engine Assembly

Engine Assembly

Engine Assembler Adam Golen measuring the main bearing oil clearance, it is super important to properly blue print the oil clearances to ensure a long engine life.

Crankshaft Install

Crankshaft Install

After the crankshaft has been fully polished and balanced we carefully wash it before installing it into the block for the final time.

Piston Install

Piston Install

Once the rings are installed on the pistons and greased we carefully install them into the machined block.

Completed Short Block

Completed Short Block

Here is the short block fully assembled and ready for the top end.

Cylinder Heads

Cylinder Heads

Cylinder head machined and ready for components to be installed.

Completed Engine

Completed Engine

Engine fully assembled ready for dyno testing.

Dyno Testing

Dyno Testing

Dyno testing allows us to ensure the engine is running properly before we ship it out. We can also retorque all of the fasteners and make sure there are no leaks or noises.
