So finally after 3.5 years of ownership I am finally going to disassemble, clean, inspect, and reassemble the matching numbers motor to my 1970 GTO. I am curious as to its story and its a chance to give my youngest son a bit of engine 101 of his own. I've so far got it down to the short block but still no rotation of the crank so far. I think the pistons are rusted in the cylinders and just need time to soak. Haven't seen any glaring damage except a well bent push rod.

Thanks for sharing. The real story will come when you flip the engine over, remove the oil pan and start removing the main caps and rod caps, and seeing sort of damage has been done to the crank and connecting rods. I'm glad you are taking your time and not rushing the disassembly - it definitely is giving you and your son time to go thru the engine in detail.

Poor Pistons.....Justa like ours, out of the playoffs early.

So went on a marathon reassembly of the motor on Saturday morning with a good oil down of everything and got the motor back together and painted in 5 hours. I feel like I've been run over by a Mack truck, lol. All I found was a bent push rod and a broken ring land on a piston skirt. Cylinder #2 had enough pitting in it from rust to keep the rotating assembly from turning over.

 

 

and now back to the rear gears and headers install.
