I need a little guidence on the rebuild of my 94 z28, the motor has been sitting for over 1 year now since the block was cleaned and borred and pistons, crank installed, I have been oiling the pistons and turning the motor by hand to keep rings from setting, now I have everything to finish the job I just dont know the order I should go about doing this, oh freeze plugs are in also. So what next and so on?

 

If your machine work is done, and the freeze plugs are in, the crank/rods/pistons are in, then I owuld say stab the cam into it. Then the timing chain/timing cover, the oil pan and heads/intake.

 

thanks man I just wasnt sure in what order to do everything and you cleared it right up. there is some surface rust on the lobes of my cam from sitting, should I just take an emry cloth and polish them? also I had my intake powder coated black and I want to polish the top rails how should I go about doing that?

 

i would soak the cam in some rust penetrant and try to "wipe" the rust off with a rag before i got anywhere near it with any type of sandpaper

 

Emery cloth will be just fine.

I stick the cam in first, then the rotating assembly, make sure you have all your oil galley plugs installed.

 

any particular reason why you do this?

and yeah, emerycloth will be just fine, BUT, it better be a VERY Fine grit. like maybe 2000 grit. and tear long strips, and lightly go over the lobes, while holding the long strips from the ends. this way, the cloth is resting on the lobe, not being pushed onto the lobe by your fingers. and it would help if you had someone to rotate the cam while your doin the sawing motion with the cloth. you can use eng. oil or wd40 on the cam while doin this to make it work quicker/smoother.

 

Wouldn't you rather find out that you have a cam to rod clearance issue as you are placing the first rod in rather than as you are putting the cam in once the rotating assy is installed and torqued?

Also makes putting lube on the cam journals before they slide in their bearing much easier with the crank not in the way.

Just they way I was shown to do it by the people who had done it for decades before me...

 

very good tip. really would be helpful in a stroker assembly like mine. lucky for me, mine fit fine. I did have to pull mine all apart though when I broke the rear main cap due to my main studs hitting the bottom of the oil pump. that was not a happy day. but, new cap, line hone, good to go.
