1st time assembling an IA II short block
Not sure why nothing attached to the last post. I'll try again.
Assembling a friends 535. I cleaned the block today and while going through the bolts and parts he brought to me I found these plugs. I have heard there are some screw in plugs that must be installed behind the bellhousing but I dont see where they go. The freeze plugs and screw in plugs are already installed there. The Bloch is supposed to be ready to assemble. Be picked it up from a machine shop because they had it for a very long time and were not working on it. ..any way..where do these go? |

Those looks like the screw in freeze plugs that go in the sides of the block. 3 on each side of the block. Also that is the option screw it plugs but it normally comes with a brass plugs that looks like it belongs to a plumbing section.

They are 1/2" pipe size with an o-ring to seal them. ..the freeze plugs are another thing that threw me off. They look to be press in plugs not screw in.

The only definitive marking on the outside of the block is this "stamped" Indian Head.

Looks like a IA 1, not a 2. The 1 had press in freeze plugs, at least my tall deck did. I don't remember where those plugs went.

Never had an AI 1 block.
But I'd look where most sizes of that type go? Oil galley plugs, one for oil hole by the distributor. (the one behind a freeze plug on rear of block is usually forgotten?)

That's an Indian Adventures (IA1) block you are describing.

I was thinking one in rear, 2 under cam timing gear (usually press in on stock block) one for the hole by distributor.

Those may not be for the block they look like the plugs for a custom aluminum oil pan to access the bolts or studs inside pan

look like hydraulic plugs to me. Could be what richie says, I have a pan like that and it was reg pipe thread/plugs.
Should be a good block, i had no problems with mine. What is bore size? Make sure you check the hole where the clutch rod would thread into. I have heard they can be thin there and leak. Mine did not, but thought i would mention it. Also, anything above 4.375 bore, you should have it sonic checked,as there is some casting shift around the 6/8 5/7 cylinders, that may require a sleave at bores above 4.38

Thanks for the help. I guess they could be from something other than this block. The owner just brought me everything he got from the previous owner/machine shop.

Agree with Richie. Those look exactly like the plugs that are used to access my Moroso custom oil pan bolts.

Finally got the pistons/rods in. Have to throw out a big thanks to Scotty G @ Scotty's Race Engines in Spring Hill, Fl.
Checked deck height, got the cam degree'd in today, rings filed to fit and assembled. After I took the pics I put the oil pump and windage tray on. Next up is just to fit the oil pan, and timing cover. |
