Change in plans. Another new build begins

Dang, I look at the pictures, then I look at the pushmobile here in the shop and I wish I would have kept that stuff. Did okay for what it is, but those 598s and 632s are brutal. Compression, cam and heads and I think it would have perked it up.

Hi Cole is that block front oiled. Can you explain the main oil line routing in the valley area. Are the lines going to the rocker feeds teed off the line as well. Hard to tell without better pic. Are the cam bearings restricted in the main bearing saddles and if so what size.
The line in the valley again, is it coming in from the back of the block from a bulkhead fitting?
Where does the second smaller line go to that comes off the oil filter adapter.

He already did right above your post and nobody asked him anything

Can you take a closeup picture of one of the main bearing saddles.
I think I see something in there like a restrictor but it's hard to tell.
We need some more photos to go with the questions. Lol
Thanks
 
The photos pittsburghracer put up are the only pictures of the inside of that thing. I never took any. I did some stuff other people say not to do and if it all blew up, I sure wasn't going to show anyone.

Did you restrict oil to the cam journals? If so did you do it by drilling a smaller hole in the cam bearings?
Did you block the passage at the front of block going up to the driver side galley.?

Does not look like it blew up to me.
Can you share the rational of some of the oil plumbing.
What in particular did you do that others said not to do.
Don,t worry I,m not holding you responsible, just curious.

Lifter bores, cam bearings, rocker gear are huge internal leaks that the system can tolerate at 3000 or less in a street car. Everything was done to control all that oil, supply just what was needed, where it was needed, and keep the rest on the crank. Everything was done for use with solid lifters, either rollers or flat. Hydraulics would need a different approach, but hydraulics would probably not be used if the engine was expected to go 7500+.

Lifter bores were bushed. Just a nicer solution than the tubes. "Crossover" was not used. The oil to the left galley was blocked at the main bore and left dry. There are other ways to do it. That galley only lubes the lifters. Not needed with a solid cam. Cam bearings were left alone. Oil to the cam bearings was restricted way down at the main bore.

The rationale was to eliminate the leaks AFTER the oil got to the mains and keep that oil on the crank. Except for a small squirt on the cam bearings, all the oil in the right galley goes to and stays on the crank.

I bushed the lifters and restricted everything else except for the main bearings. No crossover. The left galley is dry.

What is the size of the restrictor to the cam bearings.
Is there a tee fitting threaded into the main line in the lifter valley. Hard to tell from the pics.
Is that tee fitting restricted.

What was your reasoning to run the braided line in the lifter valley. Why not just use the original
Galley. It would still function withe the bushed lifters
 
Well the good news is the crank checked out good on the mag test but the .020 bearings are not in stock at my local Pittsburgh warehouses or ohio Summit so they are coming from out west. Oh well that will give me extra time to clean the block, file fit the rings, and check the rod bearing clearances. Looks like a busy week.

Can you shoot some more pictures of the block?

If it was up to me (and it is in a way) I would take close ups of everything as I like to share ideas. BUT I didn’t do these mods and Cole could lose a potential customer by me sharing close ups. He has a beautiful shop in Pa that he works out of doing chassis and engine rebuilds. Everything that I posted in the pictures has already been done but everyone adds their own ideas. Cole relies heavily on restrictions going to different areas such as the heads. He restricted in the block and I restrict in the Head right under the rocker shaft so if I want to go up or down in size it’s easier for me.

Well my least favorite job of an engine build is done. I took advantage of a 70 plus degree day and got the block all nice and scrubbed down. Best thing I ever bought was two of these engine stands with the hand crank on them to turn the engine over. Cause boy do I flip them over lots while cleaning them. Picking up the crank and rings tomorrow then it’s go time. I’ll wipe the cylinders down with transmission fluid and bag this thing till tomorrow. Hopefully early next week grab a set of my Edelbrock heads and throw it on my porting bench for a touch up, valve job, and find a set of valve springs up to the task.

Well after spending 1 1/2 hours in the gym it was shop time again. Main bearings are supposed to get here tomorrow so I figured I would gets the rings all file fitted. Hopefully get them done tonight but it’s getting late

Doing a little bit of hand crank polishing today with some 320 grit paper and blaster. It might take me 1 1/2 hours or so but that’s 120.00 savings in my pocket, not there’s. Hopefully get time to check my bearings clearances and start putting the shortblock together this weekend
 
Well I finally got around to checking the main bearing clearances today and I’m very happy with them. Set the crank in and set the thrust bearing and torqued it down. Thrust clearance it right where I like it so later in the week I can check rod bearing clearances, throw the already file fitted rings on the pistons, get it assembled, and degree in the cam. It’s been way to long since I’ve done some head porting work so I am really looking forward to it.

What main cap stud torque do you use?
