Have had this 440 sitting in the back corner of my shop for years..cast 1975. Any specific application? Cop car? Pulled out of a 2wd 77-78 truck, but don't believe it to be original.

per the top pad is there a partial VIN stamping on the pan rail?

6T440 E
9 5

6 = 1976 model year
T = Trenton MI engine assembly plant
440 = cu.in.
E = cast crank

9 5 = Friday 9/5/75 engine assembly date

Thanks, tried to read the partial vin and was unable to..will try again tomorrow.

if it has a VIN it was a passenger car engine

wasnt E 1970 year, it is externally balanced looking at the balancer

The balancer should be stamped saying cast crank only.

E440 is 1970
As Dan posted, 440E is cast crank

Thanks Dan!

So how is this a six pack bottom end?

If it has the heavy 906/908 connecting rods, some may consider it to be a six pack bottom end.

the OP appears to be asking the question .....

is this a mid-'70s Six Pack Bottom End?? * probably NO heavy rods
does this have a Steel or Cast Crank? * CAST crank

* at least when originally assembled

6D162051 = C-body from Belvidere, IL

A 76 block, cast crank and we're talking about this maybe being a six pack bottom end?

Is this still Moparts or has the site been hacked?

Ok,excuse me..heavy rods/big balancer..had always heard of it referred to as a 6 pack rotating assembly..It is definitely heavier appearing (balancer)than the std cast crank 440 of the era that I've dealt with.

Balancer is what's weird, I have a 74 or 75 motor home block still together with a steel crank and the big rods, But a thinner beveled edge balancer that doesn't have the balance ring. I have a police 77 cast crank balancer, but I don't think I looks like the one you have either, I'll look tonite to double check. Only thing for sure is its a c-body block, not what's inside.
I checked, neither one I have look like yours.

Actually E440 is 1969.

Yes, my mistake. Can't blame it on a fat finger typo.
