Starting late in 72 most 440's got the cast crank which is a special external balance with the exception being some of the truck and 4-speed engines.

Would it be internally or externally balanced?? How do I tell??

The harmonic balancer should read on the outer ring as follows; "440 cast crank only" It will vibrate with the 318 flywheel unless it is balanced for a 440 cast crank. 392 gen III hemi on E-85 727 trans Dana 60 10.02@134

It can be used but it needs rebalancing as mentioned Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

It was a very late built engine. Dan Dan. I noticed in your sig, Brewers performance. I'm on that site in another tab looking at the bolt on weights. Are those weights just for the flywheels you sell, or can they be used on a stock flywheel?? Looks like if I want to do a swap of either the 360 or 440 I need a new flywheel Ugh. No one said it was easy, but now I need to decide what engine to swap

If you were using a Mcleod wheel you can change the balance by changing the weight kit you bolt on. Dan A833 4-speeds, parts & services http://www.brewersperformance.com/

The graphic below shows how to externally balance the 318 flywhel for a 440. 7121818-castbbfw3.jpg (1160 downloads)

Regarding the crank pilot hole, by now I'm sure that most are aware of the roller bearing that is available. It fits in the torque converter recess in ALL crankshafts. It seems to be a better design than a press in bushing.

The register installed bushing/bearing is fine but the pilot shaft still needs a hole in the crank to clear the tip of the shaft. (or cut the tip of the shaft off) The INTERNET, the MISinformation superhighway

Looks ready to run, smooth no rust, no glaze, pinhole to a balance hole but not affecting service. Its 14.5 in diameter and 11" clutch surface. probably 30 lbs specs to a big block forged app. $40 plus shipping if you want it. Ill post in sale items too.

If you have a bellhousing that accepts the big 143 tooth flywheel or the smaller 383 housing that accepts the 130 tooth wheel. You will not engage the starter if you use the wrong combo. Then the major problem: A real 318 flywheel is drilled for a smaller clutch. It will not fit the 10,5" scalloped unless you drill it for the bigger clutch. And, you do not want the 440 torque through a 318 clutch. My How do I know? Well, been through it, except I tried to use the 318 on a 340, same issue unless you can accept a weak clutch....
