Larger plug just above the filter.

 

is it just a threaded hole?
if it is then its nothing...thats where a manual clutch pivot would go on a sbc

 

It looks like it is for a old school mechanical clutch . It should go straight through to the flywheel area .

 

Cool,
I cant remeber if there was a plug here or not, what about justa bolt?

 

Nothing.

 

I didnt put anything there when I put my motor back together.
On a seperate note what did you need to run the oil filter w/o the cooler? I'm considering removing mine...

 

an oil filter adapter, they have them in summit

This it?

 

yes

 

I just stripped my oil cooler off and used the existing adapter plate, it looks exactly like the one in the photo. I assume that this works. I had to get new bolts to replace the studs though.

If this is not the way to do it then please someone tell me.

 

it is, you are correct, it is the exact same adapter, swaping the bolts is all that is needed

 

What benefit does removing the oil cooler have on the motor?

 

Do you by chance know the size you used?

 

Dont remember, take the stud to the hardware store and match it up with a hardened automotive bolt. It is a common size.

 

I believe its 5/16-18 thread, 1" long maybe?

pull a stud and take it with you
