Sure looks like a forged crank to me. Can't really tell on the timing chain?
Like Dave said, the compression will be real low and you should put higher compression pistons it if you want any kind of performance.
The 2 360 motor home engines I rebuilt had really wore out heads on them and cracked exhaust manifolds from the heat they endure. Granted these were SB and I imagine a 440 won't work as hard.
When I was driving my parents 73 360 equipped motorhome, I would have killed for a 440.
Got a picture of the top with a piston at TDC?

No picture at TDC. I asked the seller if he had measured it. Pretty soon he'll tell me to take a hike!
The motor does look really clean. May be a good starting point for a mild build.

What?! With stock pistons/compression? Put a modest top end on it and away you went? Nice.
Quote:yup...never even tore into the short block....906 were stock except i used mopar templates.... we threw some big valve 915's on it...went 12.0X all day long shifting at 5200-5400 launching at 3000 rpm... 14.5 x 32 tires with 4.56 gears...it would also float the lifters ....but that was built in rev limiter in high gear...LOLQuote:Quote:..I ran one for fun... .533 Mopar Hyd ...

Even with the low compression, it's a torque monster!
my builder took it to .040 with no problem.

Smoggers can do ok for what they are but if you ever drive one with an honest 10:1 you will know it.

Oh, no doubt, but some of us make do with what we have.
It's kinda hard to justify new pistons, balance and bore when the stuff that's in there look SO NICE.
Besides, 12's in the 1/4 mile ain't to shabby out of a budget build like you can do with an RV/Truck motor on the cheap! Those are some of the funnest bang for buck motors you can do!
I can guarantee you my car (3,100 lbs.) even with low compression is a low 12 high 11 second car as it sits.

Hey I've been there, done that. My previous engine was a 76 440 with a new set of rings and all the bolt ons. It was ok but I could feel it wasn't making the kind of power it would with some compression. The smogger engines are much more sensitive to running too much cam or too tight of a converter. With the low CR the bottom end is softer.
