Block Head and the Piston Rings

I ordered a cylinder block, pistons, rings, pins and clips Monday.

I had been waiting on a quote from a local machine shop to repair a small ding in the old cylinder block. The cost to repair a nick at the top of one of the cylinder sleeves, hone both holes, resurface the top of the block, purchase new pistons, rings, pins and clips was +/- $5 the cost of the pistons/rings/pins/clips and refinished block on eBay.

The new pistons are the same brand (Emgo) that the local shop was sourcing for me. The pistons are 0.040 over.

-As Dietrich says, "There is no replacement for displacement!"

I'm looking forward to the arrival of the new parts. I can try to sell the old cylinder block, or bring it to the office and use it as a pencil holder.

The transmission camplate arrived a couple weeks ago. The transmission is ready to go back in. It seems to shift through the gears with ease. I'm hoping that it still does once i get it back into the engine! The cylinder and pistons should arrive Monday. I'm still having the local shop seat the valves. I'm hoping I will be able to pick the head up by the end of the month.

Next parts to order is a stock oil tank and left side cover. I can sell the aluminum Webco oil tank on CraigsList to ease the blow to the pocket book. Returning this thing to (mostly) stock will be worth it in the end. -at least that is what I keep telling myself.

It is starting to come together, but the list of parts still needed seems to grow every time I look at it.


  1. You still need to get the cylinders bored for the pistons, right?

  2. The description that was provided said it was ready to be installed. In the specs it said there was 4.5 thousandths clearance. Most places talk about the British tolerances being big enough to drive a truck between the piston and sleeve. I'll check the manual and see where it should be.
