They can also check all your clearances and sell you the correct bearings, etc. so you don't have to wonder or worry if they're right.
Step 2. REAEARCH, plan and build it as big and powerful as you can or you'll wish you had.
Other than that, there are a lot of resources on the web as well as in print that go into detail about assembly.
Step 3: After getting the parts back from the machine shop, be sure to measure the clearances yourself to make sure the dimensions are correct.

make sure you get the piston side clearance right and the piston gaps too so the damn thing doesn't burn oil.

in my experience those 2 things are the most critical.

My vote is affirmative. Not every rebuild is the same. Some times there are issues encountered and how to get around them can benefit others. Most text books assume nothing out of the ordinary happens and everyone knows that stuff happens most of the time in real life.

thanks for the input, guys. i have already started my photo documentation. i was hoping to put the bottom end back together tomorrow but it looks like there is a problem at the machine shop getting the crank to balance out. looks like the brand new flywheel i got from jegs is out of whack and will have to be returned/replaced. that's going to slow things down a bit.
anyway, this is going to be a 'by-the-book' type rebuild as far as assembly but i've already spent a considerable amount of time on the little things that often times get overlooked or are just too obscure for the average joe.
i'm still shooting for start-up next weekend. we will just have to see.

I want a write in ballot here - how about a "sticky" for engine building tips. There are some things that the beginners take for granted that you do not want to learn about the hard way. Save some retyping every time this comes up. I would use it.

How about a "start-up" after rebuild thread. This is where I have all of my problems. This thread must include a large "troubleshooting" section.

Just a thought.

Heck yea. It would give me another reason to believe I can do it myself, get in way over my head and have the geniuses on the forum bail me out with their wisdom again.

Some times Turtle you kill me lol. They can not just jump up and balance the crank they first have to balance the pistons and the rods both big end and small end. Then you weight all of the components to get a bob weight of which you would add to the journals of the crank to balance it. Then you put on the harmonic balancer and do that and then the flywheel then if it is a standard gear box you would add the hat or as most call the pressure plate and balance everything as an assembly. Whewwwwwwwwwwwwwwww. That way the motor will be smooooooooooooooooooooooth.

I think it would be a great idea to have a build thread.

hey turtle, fair question. part of the trick of this build is that i'm using a late model roller block. freaky thing i learned about this is that the 1 piece rear main cranks are internally balanced on the front and EXTERNALLY balanced on the rear (WTF?).
looks like i'll be getting the crank this weekend afterall so i should have the bottom end done this weekend, short of the cam (which hasn't shown up yet). either way, i should still be on for installation/start-up next weekend.
wish me luck!

Do the rebuild, take lots of pics, and be sure to post them here. The more the better IMO.

I would love to read about your buildup and see pictures. If you take the time to do it I would read it. I too am always looking for something I might overlook in my rebuilds.

I too am in the middle of a build up and I agree the ford blue has to go. I put the red pan on this week and it really looks sick beside the blue.

fine, i'll hit the fuel pump area today.
BTW, it didn't take as long as i suspected for people to assume it's ford blue. that's actually PONTIAC blue. i chose it for several reasons. when i do the full thread, i'll explain my choice.

i've never balanced an engine. You just put new pistons on and put it together. I don't think a fine tune balance is worth the money for the kind of engines we build.

The glyptal has always bugged me. I just don't see how you get the adhesion. I worry the stuff will bubble up flake off and make a real mess out of the oiling system.

You haven't told us too much. Do you have a stroker crank?

The glyptal will not come off, if you are worried, just pull the intake off your engine and poke your finger around in the rear drain hole (next to distr. hole)..you'll find some nice surprises there. The glyptal will not bubble and flake, ti's chemically resistant and thermal resistant to anything the engine will theow at it...it's seriously good stuff. I've used it on engine blocks, heads, valve covers, differential cases and lids..and so on. I've never had it come off, not one flake
