440 engine numbers

[Old Tired Rebel]

I went to MyMopar to look up my 440. Here is what I found and could use a link to find the other numbers I have.

4006630-440-1 = Industrial RB Engine

I wasn't able to find these numbers so if some one has a link I can use it would be helpful.

R7

7 T 440 E

4 22


The heads I have are 4006452 and found the specs on it.

76-78 400- 440

81.5 CC

Intake valves 2.08

Exhaust 1.74

The heads I have are, I am not sure of how good they are.

4006452 31 0404

4006452 30 0057

what is the casting year of this block? 1977? Not sure if you've seen this, but might help a little. http://440source.com/blockinfo.htm

It's a 78 Industrial block from a motor home.

4006630 - 440 Thank you for the link.

pure guessing,

R7?
7 = 1977, T= Trenton Mich assy plant, 440, E?
4 22 = 4/22/77 engine assembly date

Thank You I knew it was a 78 block but could be a early build.

Yeah I was writing before you responded. if the block was cast in 78 then what I said is partially or all incorrect. They obviously cast before assembly.

It very well could be a 77 block. I took these numbers directly from the side and a pad on top of the engine.

ok here is the answer, Still not sure about the R7 though.

7 = 1977, T= Trenton Mich assy plant, 440, E = cast crankshaft
4 22 = 4/22/77 engine assembly date

I was close. this will explain the R7.

Thanks Rocky All I need to do is clean it all up. How good do you think the heads are?

 

[Old Tired Rebel]

Looks I have a excellent block to build on at a later date.

no personal experience with those 452 heads but did find this on them. It seems they are a good set to hang on to.

Also on the block casting yours is a 440-1 with the -one meaning first mold/ no mold revisions. Most say these are the best to get, but I don't think it really makes a difference.

Looks like I fell into the heads. Thank you for all your help.

I know this post is old but the R7 stands for standard fuel. Just in case someone wanted to know for future reference.
