I recall a lapping bar involved?

That will be fun, bolt on, bolt off repeat.

Yes, I need to put the heads back on and get to it I guess, but I'm not actually free of "The List". Railing parts are here (the correct parts this time it looks like) and most everything for the floor and the theater cabinet finish has still not been approved so its still sitting in the middle of the shop floor awaiting yet another coat of urethane, this time sprayed on I guess which I'm not sure how to handle...outside in the cold or cover as much as I can in the shop.

I did pop the main bearing caps off and order some o-rings I think are correct for the oil tubes and yes, the 1982 ones just crumbled when I tried to remove them. I also dug through the metal pile and I think found stuff to hold the buckets in place while the engine is upside down, just easier to use bars than cams I was thinking.

As I hit post I remembered what was bothering me last night...it seems like I was supposed to order something else....o-rings for the rear main bearing cap! ...so another order and another $8 shipping on $3/100 bag of o-rings

Re: FrankenFerrari - V12 ferrari 308 part 4

Today I put the heads on.....just shy of 2.5 hours of work. Assuming all goes the plan, this is the 2nd to last time I need to torque the heads on. Set the bearings(12 hours), remover the heads 1.5hr), install crank and pistons(4hr), clay on pistons(.5hr), heads on but I'm thinking just snug them(.5hr), timing chain and cover (8 hours), remove timing cover(2hr), remover heads(.5hr) inspect clay(1hr), heads on for real(2.5hr), timing cover(8hr), then the rest of stuff.....12-20 hour, so like another 50 hours for work before its ready to go back in?

I think I've now crossed the 14 year mark BTW

I use PVC pipe to hold cam buckets in. It works and was cheap.

I didn't even think of plastic...i found some 3/4 copper I was planning to cut but now it looks like a trip to lowes....but anything outside the house is still a big deal to us as my youngest is not yet vaccinated so there is a protocol to follow and i sort of just broke it by placing the order myself but as long as I don't go out unsupervised that should be acceptable. Today should be spray the cabinet day, which means dry time, which might mean car time again later hence a small break in protocol now to be sure I'm ready then

It was a very expensive $3.48 pipe.....but I'm told look how much we saved!...hmmmmmmm

edit: it looks like we'll be saving even more as all Lowes within a 30mile radius are being scouted for sale pricing. No doubt they will look nice but this many usually means I will be doing the digging.

With that sorted I was free to flip the engine over. I don't know why but this caught my eye

The intake valve are a bit closer to the cylinder than the exhaust, butr pretty similar...maybe 2mm clearance? Way, WAY back when I was trying to get the heads to fit the top row of head bolts I want to save, but keeping them as-is meant moving the head 2mm lower than factory.....hmmmmm the means bigger intakes will fit! Then the bore went from 81mm to 86mm and that means all the valve can get bigger.....and 14 year later here we are

Blue the mains

Lapping bar in....hmmmm... sure looks like only the 3 center bearings are toughing...that is the direction the block was wrapped after welding but I thought it had been corrected, only mostly corrected it appears

and straight, ready to start the caps and that only took about 1.5 hour including the bucket retainers and adding a handle to the lapping bar.

Re: FrankenFerrari - V12 ferrari 308 part 4

As the time to assemble appears to be growing near, I'm semi rethinking my decision to not make this a redhead. I was looking at some old pics and .....hmmmmm.....

Tonight after a morning of plant sale shopping and an afternoon of railing building I got another 1.5hour in the shop. I'm not sure how useful this step was but I cleaned and oiled the block and 1/2 the lapping bar and dropped the clean side of the bar into the block thinking the block is now straight so I want to cut on the caps. Attachment: 20211106_182930-resized-1024.jpg [ 287.99 KiB \| Viewed 2691 times ] Bearing 4 was loose to start with and the bar cut more on the block on the center 3 so I went ahead and sanded #4 a bit before doing any lapping Attachment: 20211106_183629-resized-1024.jpg [ 206.63 KiB \| Viewed 2691 times ] then fresh compound and caps on and get lapping...I was working hard enough to twist of my welds Attachment: 20211106_184756-resized-1024.jpg [ 191.7 KiB \| Viewed 2691 times ] but eventually it turned with the caps torqued Attachment: 20211106_191837-resized-1024.jpg [ 267.28 KiB \| Viewed 2691 times ] Next up is clean all that goop off and start measuring. Its my hope that the only error will be loose bearings and that gets sorted by sanding the caps but we'll see in the next episode.
