Gang, I am so excited that today I finished the tear down part of my 440- I have 2 questions that I am not sure why they are this way. First the front freeze plug on both sides of my block are rubber and the others are like normal I have not seen it anywhere in what I read- does anyone know why this is??


Number 2- when taken off the main caps off the block the #3 cap bearing didn't come off like the others. Again this I haven't read about, could it be a bad bearing or something that is special for the #3.

 

1st Question: those are the cheap rubber replacement ones someone installed to repair a leaking freeze plug. Get rid of it.

2nd Question: #3 main bearing is a thrust bearing. You will have to use something to knock it off or pull it off. It overlaps the sides also.

 

You are the MAN!!! thank you- would you think about moving to Pittsburgh as a personal consultant- I will get rid of the rubber trash, and I assume the thrust bearing is normal to only on the # 3??? Thanks for the help, I added more to my album of the teardown. I will drop the engine off at the machine shop in the next week, then I will see which way the build will go from there. I look forward to your input on some things, thanks Joe

 

when rebuilding replace the freeze plugs

 

Looks as if the #3 bearing has alot of wear, also is fully grooved. Was this a H P motor? May have a pinging problem. Calculate your compression ratio before assembly. Dont want to have more than 10.5 to 1 for the street. This may be pushin it depending on your elevation.

 

Thanks Gary, is there a "simple math" to calculate compression, I would think a 9.0-9.5 for weekend driver, thoughts? Joe

 

Try this one: http://www.kb-silvolite.com/calc.php?action=comp

 

This is the easiest and most accurate one I have ever used.

Thanks bremereric and 500, I will get these measurments and see what I have and will get. Joe
