I enjoy working on these trucks--but-- yes it will hurt. About a $1,000 dollar hurt. Bad thing is that I knew better. The Jimmy sat for around a year and the gas smelled really bad, but I drove it 4 miles to the gas station and back.

That really sucks to hear about your engine. I have never heard of that. The carpet really looks great in there!

Thanks,
I hope to have the engine back wednesday. I will assemble it AGAIN and hope to have it in and running this weekend.
The bad (old) gas is more volitile and can ignite and explode while in the compression stroke. That exploding gas puts pressure down on the piston while it's still comming up. Then it fires again when it gets to the top when it should. All this creates tremendous heat and pressure in the cylinder. Thats when the ring landings cant hold the ring, and it breaks.
NOW you have more heat and pressure going down the side of the piston, heating the side of the piston and getting in the crankcase. Now you also have pressure in the crankcase hammering up on the ring landings also. Every thing goes to s#!t.

Got all my machine work done. Decked the block and bored to .040 over. Turned the crank .010 under. Surfaced the heads.
This time I installed new pistons and rings. New bearings through out. True roller chain and roller cam with roller lifters. New harmonic balancer because the old one had a wobble. More important is that I replaced the old gas.

Congrats on getting it back together. Glad you got to enjoy it with the top down.

Thanks,
I'm now going to install the Auto Meter gauges into my cluster by attaching them to the back of the original lens. Clean up the wires behind the dash.
Need to center the steering, It turns sharp one way but not the other.

Time to move on to the next project. Hate to see it go. This thing has amazing power on the highway. When you want to pass, It gets it done in a hurry. If I was to keep it I think I would install a 750 dbl pumper, roller rockers and a set of headers. From what I read that would put me close to 425 HP and torque would be way up there. But it all ends here for me on this one.
It's Ebay sale ends at noon pacific time tomorrow. Wish me luck. DENNIS
