I believe it's from a 1959 Chevy car of some sort. I believe the engine is seized and will not turn. It has been sitting in the elements for many years even before I bought it. The head is full of water.
My question, is it rebuildable? That is if the block is not cracked. Should I take the time to tear it down clean it up and have it inspected for cracks in prep for a rebuild? | | | | | Joined: Jan 2007 Posts: 446 Shop Shark | | Shop Shark Joined: Jan 2007 Posts: 446 | | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 |
If you want to know if it is rebuildable, take it completely apart and bring the head and block to an engine/machine shop. Have the head and block cleaned and checked for cracks. Find out the cylinder bore (over-bore). You might as well have the crank checked also.
The shop might give you an estimate for the necessary machine work and maybe an estimate for a total rebuild.
Maybe someone else will post more helpful information.

Then the cost may be prohibitive. Even if you get the head off, you may have to break pistons apart to get them out of the cylinders, only to find them pitted beyond repair without sleeving the engine.
But you really won't know untill you take it apart. | | | | | Joined: Jan 2007 Posts: 446 Shop Shark | | Shop Shark Joined: Jan 2007 Posts: 446 | It sounds like it may be better to find a 235 in decent condition to build then. I just hate to see the old engine behind the barn going to waste. I probably should just haul it in for scrap. Besides, 235 engines are common enough. I have to find a truck to put one in first anyway! I have my mind on a '36 thru '41. | | | | | Joined: Jun 2009 Posts: 235 'Bolter | | 'Bolter Joined: Jun 2009 Posts: 235 | Hey, Wasn't there someone on the forum, I can't remember which one, asking where they could find head bolts for a 235? They said they were having no luck - maybe you could part out what you don't need and make a little $ towards fixing another?

If you want an original motor, then find a different one to build. If you want a modified, then the one you have is perfect for putting in larger pistons, a new crank, bigger valves, and a new cam shaft. It is a growing fad now to hot rod these six cylinders with extreme intake manifolds and headers for exhaust. My father, a long time drag racer intentionally puts his motor blocks out in the elements for years by his shop in order to "season" the block. He says this is crucial for a build. Now as for the reasons or facts as to his actions can be disputed, but the old school car club guys swear by this practice.I think it is cool to look under the hood to see what appears to be an original motor, untill it fires up and runs a quarter mile faster than a stock v8 heheheheh.............. | | |
