Early CJ2A engine/GPW engine

 

GPW blocks/engines are out there, but commanding big money before rebuilds, if interested, i will shoot a note of someone that i know that has a completely rebuilt GPW engine that may be ready to sell it.....

 

your engine is a very early 45 2A engine, delivered in a 45 serial numbered around 10200...

 

my 45 #10163 has it's original engine, and it is #10170.....

 

I wasn't aware of that, and wondered about the advisability of grinding the CJ2A number off or leaving it--- guess I could grind it off & put my GPW ser# on there

 

  I have looked around some, and have found out about GPW blocks bringing large $'s, not to mention that one needs to be quick on the trigger to get one.

  Me buying a rebuilt engine would be akin to a cobbler buying shoes... Thanx for the thought tho, Low.

 

Sean, I've answered your PM, and will get you more info when it warms up a little. (about -8*F out there right now, WC probably about -15)                 BW

Got it, thank you!  Wait for it to warm up!  I'm not in any rush (it's below zero here too, and I won't even go outside )

If you do decide to grind off the CJ s/n, get a photo first please!

I have a GPW block that was in my 2a when I got it. It was seized up. It's the one the engine plate I sent you came off of. I took it apart and sent the block to the machine shop. They said it needed to be sleeved. When they did the rough bore on # 4 the cylinder caved in a little at the bottom. A hole about the size of a quarter broke through from the water jacket. As you know, I got a different block and am on my way to getting it put back together.  Question is, is this GPW block I have any good to anyone?  Here's the # GPW259679. Do you think someone would want to try and save it?

Do not scrap that block.  It is very likely that it can be saved and live on.

I'm not a machinest but I have found machine shops that take on these challenges and are successful..  My GPW block was cracked in lots of places and the machinest who does my engines has a sub whose only business is cast iron block repair.  A couple of years back a friend blew up his 1967 corvette 427.  It was not a minor explosion.  Parts flew out the side of the block and pan and most of the internals were turned to scrap.  He found a machine shop that was willing to take on the repair and they used a bunch of techniques to bring the block back from the dead including use of some kind of cement around a hole in the cylinder.

The best I could say is find a machine shop that takes on these types of jobs of restoring old or industrial engines.  They are out there!  You will not have luck going to the shops that specialize in modern volume production repairs or tweaking of rice rockets. I wish I could help further but as mentined there have been some experiences like yours on the g503 board so that might also be a great place to post.

Good luck and we hope you can save it!
