My block came back from the rebuilder with a box full of parts that were replaced like the rockers, push rods, etc. as well as the bolts to a few things that I need to reinstall like the oil pump, fuel pump plate, fly wheel. I have identified where all the bolts I need go except these three. They are the same size, about 1" long. They are not the three that hold the big pulley to the dampner. I already found those. Any idea where these go?:

This is the block that went to the rebuilder.

are they possibly go into the block as plugs?

look like the 3 camshaft sprocket bolts to me.

What he said ^^^ cam sprocket bolts

Are the heads smaller than 1/2" ?

If so, I'd agree with these guys. I can't remember what size they are for a SBC.

If they're sludgy, they were INSIDE the motor, and if they're gritty, then I'd assume they were outside the block. Just some deductive reasoning....they look sludgy and smooth to me.:cool:

Stock cam bolts don't have that flat lip on the bottom of the head. You couldn't use a cam bolt retaining plate if they did.

They look like 3 of the 4 bolts that go at each corner of the oil pan. Remember - those were larger than the other oil pan bolts.

motor mount bracket?

converter bolts?

were there any accessory bolts left in the motor?

Nate

Thanks for all the replies. These are not the four outer oil pan, motor mount, or converter bolts. I have those bolts bagged and labeled.

I did have a new cam installed and those three bolts currently on the cam gear do not have the flat lip like Damon mentioned.

The threads on these bolts do seem sludgy.

Even though I took general pictures of the block, I guess I should have taken more detailed shots. Oh well... :-(

Let me me ask this question - Is there anything else in the crank area that I need to install besides the oil pump before I install the oil pan?

might want to take a pic of the bottom end before we answer that. but from memory, oil pump drive rod, oil pump, oil pump pickup tube, If you using one, scraper or wingage tray, and gasket and oil pan.


that is if they did it right.

Since you trusted me on the cam bolts let me go one furter. I dont think there are ANY bolts inside a stock SBC that use that flat shoulder on the bottom of the bolt head. Every bolt I can think of inside the motor uses a standard head on it.

Something in my brain keeps screaming "accessory bolts" for some reason.

I swear the answer is hanging 6 inches in front of my nose. You realize I have no ability to walk away from a mystery like this, right? Thanks, you're driving me insane! I've disassembled and reassembled a small block at least 6 times in my mind thinking about this. If you don't figure this out soon I'll have no choice but to fly to your city, show up at your front door and help you install that motor. THEN we'll figure out what's what!

Power steering pump adjuster bolts, engine electrical ground bolts on the back of the cylinder heads, engine mount bolts, stuff for mounting the A/C compressor, torque converter bolts..... NONE of which should have been on the engine you sent to the machine shop. The mind boggles.

OK, tomorrow morning I want you to call the engine shop and ask them. Sometimes they get extra bolts in with your motor becuase they happened to be laying near your engine when they got everything together to give to you. Somebody else's bolts were laying next to you stuff and it got included by accident.

3/8" x 1" three motor mount bolts left in her??

Damon, that's what my buddies at work think happened. They said these appear to be some type of bolts to mount some type of bracket or accessory and someone thought they were mine and put them in the box-o-many-parts.

But still please check for me. I appreciate your help. You've already helped me out quite a bit on this "first-time" motor rebuild.

Thanks!

Fuel pump plate bolts, the ones that hold the plate in place, two of them and the third might be the one that goes in the hole in front of the motor to that goes through tot he fuel pump rod?

MMM...if I remember correctly, those are washered bolts....and there's 2 short and 2 long, and that one in the front that you mentioned behind the smog pump is less than an inch long and bigger around.

But it has been a while since I meddled with a puny block ;)

I've been through every bolt possible (in my head) in the long block you show,,, the ONLY 5/16" nc,,, 3/4" long bolts are cam bolts. Judging from the paint (or lack thereof) on the timing cover, someone has been into this before, and replaced / changed the cam bolts is my bet. What you got back is, the machinist used the 'right' cam bolts, or there is no cam/timing set in what you got back.

Someone correct me if they can think of anything,,,, but where else in the long block shown in the post that went to the machine shop,,, is there 5/16" bolts other than the timing set/cam????

I'm thinking cam gear bolts on an aluminum (?) gear with plastic teeth.

Years ago, my Buddy, Doc asked me to help his youngest Stepson rebuild a '66 mustang 6-banger and the boy didn't have a clue!

He had taken it in and got it hot tanked first so It was clean, ready to assemble.

I was going right along and had to stop at the cam b/c the Machine Shop didn't give him back the cam retainer flat! AND he didn't even know he needed it.

Anyway, he retrieved it from the Shop a couple of days later and finished putting it together after I explained to him what needed to be done and he was fine.

I talked to him at his Mom's funeral a while back about how the engine/car turned out after all these years and he lit up and said, fine b/c of my help.

Doc was smiling right away... At a time like this remembering the good times when his wife and the boy's Mother was still with us..

I love my Buddy Doc just like the big Brother I never had....

I agree with tom3 (aluminum gear with plastic teeth)
Look at pichttp://i89.photobucket.com/albums/k214/galvanniR/cambolt.jpg

3/8" x 1" three motor mount bolts left in her??

exactly what i was thinkin!!

Look like the starter-to-block brace bolts to me...

those are definatly factory cam bolts. I like to use those in my engines because the built in washer holds the nylon cam buttons from comp I use. I dont like the lock plates as well as using these bolts and a drop of locktite

Thank you to all who gave input regarding the mystery bolts. I'm assuming all is good since all other bolts are accounted for.

I am buttoning up the motor and will drop it in this weekend.

Thanks!

I'm just finishing up my 76 350 and those are the same bolts I took out of my factory cam gear. I still have them somewhere....
