265 Chevy Engine Rebuilding Service.

Model: 1955 GM Chevy 265 4.3L OHV 16V V8.

Chevrolet Small Block 265-cid in for a complete rebuild.

Agenda for this classic engine:
Inspection, Teardown, and Cleaning.
Block Work: Bore, Hone, and Deck the engine block.
Head Work: Valve Job includes: Pressure Test, Magnaflux, Resurface, Grind valves, Cut 3-angle valve seats, New Exhaust guide inserts and valve stem seals.  Clean, paint, and assemble.
Any missing, damaged, or broken parts will be replaced.

Machine Work- Recondition Crankshaft, Camshaft, and Connecting Rods.

Order New Engine parts; Pistons, Rings, Bearings, Timing, Gaskets, Oil pump, etc.
Last step, assembly!

Now we tear it apart, looking at current condition of all the parts.  This is just the initial inspection.  Since it is so dirty, we have to hot tank it, melt off that grease, and scrub it, so we can really see the condition.  This is where we decide if any of the components need extra work or attention.

After the block is cleaned, we see the cylinders have deep ridges in them.  These are too deep, you cannot bore and hone them.  They are over 40 thousandths, so we need to install new cylinder sleeves.  We contact the customer so he can take a look and give the OK.  This is common with these older blocks.

Basic Valve Job includes: Pressure test, Magnaflux for cracks, Resurfaced to a nice flat surface to mate up with the block. Grind valves, Cut 3-angle valve seats, Lap valves, Install new exhaust guide inserts, install new valve stem seals, clean, paint, and assemble.  Any missing, damaged, or broken parts are replaced.

These heads needed new Exhaust Seats installed, years of unleaded fuel ate them up.

BLOCK WORK – Chevy 265

Customer gave the OK, to move forward with putting in New Cylinder Sleeves. We bore bore out each cylinder, removing the old and making room for the new sleeve. After, we Hone the cylinder finishing with the proper crosshatch.  Clean in hot tank again to remove any metal residue.  Deck the block surface so the head mates up nicely.  Last we put a coat of primer, then a few coats of paint.

Now that all the sleeves are installed, it’s time to Deck the block. Then we clean it again, put on a coat of primer, then final paint.

Bottom End

Block work is complete, it’s cleaned and painted, it’s time to start installing the parts and components.  Short block assembly is under way. New Cam, Main, and Rod bearings. Reconditioned Reground and Polished Crank and Cam.  Connecting rods reconditioned. New pistons, rings, gasket set, lifters, and timing set.  This classic is coming together.

Valve Job is complete, but I missed final assembled photos.

The engine is assembled and complete.  It looks pretty cool on the table with the skylights on it.
