Some background; I got the truck about ten years or more ago, I took the broken big block out of it, built a healthy 355 engine to put back in it, took the 203 and t350 out and put a SM465 with 205 back in. Almost everything in the engine, on the engine, and in front of the engine was new or rebuilt. It has Rhoades lifters, Scorpion roller rockers, TRW pistons, World product heads, and loads of other go fast goodies which I can't remember. It was balanced to a knats arse, align bored, and generally well taken of care of for a street engine build.
Then it was parked, and has been parked for years. I was starting it about three times a summer and driving it around the sections to keep it in some kind of shape. About three years ago I stopped starting it at all. Tonight I started it. The gas is about five years old,the fuel filter was dry it's been sitting so long. I used an ignition bypass button on the solenoid to spin it until the fuel bowl was full. Oil pressure came up instantly. it sputtered, and coughed and wouldn't idle over about 500 for a couple of minutes.
This is it struggling to run on the crap that is in the tank...


This is after about three minutes of idling and playing with the foot feed...

I noticed that the phone picks up sounds I can't hear when it's running. It makes a sound like it's falling apart. I assure you it doesn't sound like that in person. The lifter noise is normal for Rhoades lifters because they bleed down at low rpm's which helps smooth out a tall cam and helps it develop more vacuum at idle. However, there is a tinking noise when I was in the cab that I don't remember being there before.

But it's alive. I drove it down the road about 1/2 mile but didn't go very fast because it needed air in tires and I wanted to make sure everything was going stay firmly attached to the truck. It was about dark when I got it running anyway which is why the video quality was bad.
