There's an experiment looming in the future. I think it will be interesting enough to warrant watching this most boring progress.

Not so "boring" to me, I could stand to watch a bunch of this.

Much to be learned from your experience, expertise, and experiments. Keep it coming.

I spent part of the afternoon cleaning parts. The block is clean until it's time for assembly. All the bolt holes are cleaned and retapped. The broken bolts are removed from the block I think you'll like this creativity.

I threw the oil pan in the vat. The 2 pics are of the inside and outside. When I drained the oil, I knew there would be a story. The inside shot shows a rethreading plug that was large enough that the bottom half of the plate-nut was broke off. They left the plug in and drilled the center of it. Then there was a nut braised over the top of the plug to the side of the pan. There was a small fine thread plug in the end on it. The orifice was small enough that it took a substantial amount of time to drain the oil. The pan is going to get modded for the experiment.

hmmmm, the engine had a few oil changes at Walmart ?

I had a neighbor with a 1 ton GM truck , Big Block engine , cast aluminum pan.. His son borrowed the truck. Son had the truck serviced at Walmart as a favor to his dad. LOL Walmart guys Cross threaded the drain plug. This was near 20 yrs ago... I was told the pan replacement at GM dealer cost Walmart near 700 dollars.

After lunch, I returned to the land of nasty and ugly. The crank is polished. I cleaned pistons and valves. Then I cleaned up the mess.

Some of you will enjoy this.

It got up to 72 degrees today. I had the roll around engine stand outside removing the chevy mounts getting ready for the sbf. I rolled it inside and rolled the block outside to do some de-burring. In the bright sun, I saw places that weren't clean. I knocked all the plugs and cam bearings out of it and took it to the vat. It was obvious to me that my best efforts weren't going to be good enough. In the morning, I'll pull a clean block from the vat.

Sounds like buffing.

Don't we wish there was a vat for that.

O&S was at it early this morning. I retrieved the block from the vat so it would be out of the way of "working people".

After it warmed up, I repaired the damaged oil pan. I'm out of sequence with what I did today but it got up to 74 degrees. I painted the block, oil pan, heads and valve covers. I'm going to throw the front cover in the alum. vat and leave it natural. I'll have to be careful from here on but the weather forecast shows the cold returning.

weather wise: Tuesday was windy , rainy & cold here in Arizona.. Wednesday is suppose to be the same or worse. This stuff may be headed your way. I'd suggest a nice holiday sweater for yourself.

Working some the last two days. Expansion plugs installed and it looks like a short block.

The logic is that an assembled engine takes up less space than parts spread all over the shop.

If the weatherman is correct, I won't work for a couple of days. I have a plan to modify the engine stand, now. O&S speed at a normal cold weather pace.

so , the bottom end was good shape... the heads junk ? Camshaft?

kb426 · November 22, 2019, 09:18:03 AM

Tony, most of the internals are being reused. I'm repairing the head to be able to complete my experiment. This block is roller era but wasn't drilled for the lifter spider. I installed a roller cam and lifters to see if there was any other work needed. I installed the original cam that is needed to make the efi work. When the test is completed, I have lots of other parts that may end up on this engine. It would need a good rotating assembly to make use of the heads and cam that I have. Time will tell how this ends up.

I discovered a problem at the end of yesterday. I was tired so I quit after that. It was bothering me so I turned on the heat and went to work this am. I found 2 problems. The front cam bearing seemed to be egg shaped towards the rear of the engine. I used a razor and removed just a little material in 2 places about an 1/8" wide. I put the cam back in and everything seemed good. I bolted on the cam gear and the engine locked up. It turns out that the new cam gear is 12 thousandths shorter on the spacer part that goes through the cam plate. The old gear showed almost no wear so I re-installed it. End of that problem. Cam plug, rear seal and front cover are installed with the pan and pump. I had polished the end of the crank so the seal repair sleeve went on real nice. I put the balancer in the lathe and cleaned the snout on it. Those repair sleeves sure go on clean surfaces nice.

The good head is assembled. The repair on the other one is next on the list. O&S and out.

O&S at it's finest.

I visited the scrap pile for some materials to make mounts for the engine stand. This was a big block chevy irrigation engine stand. I reused the rear mounts. The block will have long studs put in those 2 holes to fasten the block to the stand and the bellhousing to the block. I had some pieces of 2x4 rectangle tube that was collecting rust. I reused the original mounts that I had made for the 32. There's a flathead biscuit on each side. I have plenty of room on the front for the water pump and drive. I have entirely too much in this today. Around 4 hours!
