Billet Main Cap Question, Part 2 #2049249 04/07/16 09:56 PM 04/07/16 09:56 PM

I have tried everything I can think of. Called 440source to ask if it is normal and was told by whoever was on the phone to "touch the sides with a belt sander". If I do that, wouldn't I take the chance of getting the caps out of center with the crank? Do I need to take these to the machinist along with the thrust bearing cap? (I asked about that problem the other day.) What do you guys think?

When I started getting the block ready for assembly the caps were very hard to remove from the block. So hard, I had to remove the studs and take a dead blow hammer and smack them back and forth (forward and backward) about 6-8 times each before I could pull them out with my hand. I don't know how the machinist got them in the block.

Do not remove material from the side with a belt sander or any other tool. Chamfer the corners only. A flat file works fine. Last edited by Moparteacher; 04/08/16 12:09 PM.

They are supposed to fit tight , if they just drop in then that is not good, but you should be able to draw them in with the bolts fairly easily ... as mentioned measure the cap and measure the block ... That said did the person really tell you to touch the sides with a belt sander ??? .. running up my post count some more .

The caps already have a bevel on them but he has the right side way lower than the left side. The caps MUST be installed squarely. 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time

You may be right but owning a set years ago I know they are tight as are my keith blacks. I had a set on my 500 inch engine that ran 275 passes running 8.60's. No block fill, no girdle, but went I tore it down the block was cracked up through the usual place. No warning no water leakage just cracked. Better than stock? YES. Better than aluminium? NO WAY. 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time

Leave the file were it belongs, in the tool box. Chamfer maybe, side of cap absolutely not. If they needed it the machine shop would have done it before the line bore 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time
