I have an elderly friend who raced a Max Wedge car in the 70's, and he collected a lot of MW specific parts when he ran across them. He asked me to sell the stuff for him, and I ran across one piece I'm a bit confused about. He has a crankshaft with a casting number of 2206158, with an 8-bolt flywheel flange. None of the info I've been able to find says that casting had an 8 bolt flange. Any idea as to what it may have been in originally would be appreciated.

Yes, the hemi has an 8 bolt flange. I guess the charts I've seen do say that casting was used in 426 cars from 1963 to 196, so that must be it. That casting was also used in 1971 to 1977 truck 440's, and I believe the trucks also used an 8 bolt flange, so it may have come from one of those as well.

The 2206158 forging was used in various RB motors from '62 until the end of production. The flange could have been drilled either 6 or 8 holes.

There is NO Max Wedge crankshaft with a casting number!!!!!!!!!!!!!!!!!!!!! Unless your friend had the only Max Wedge in history with a cast crank.
A casting number is part of the mold into which the molten metal is poured to form the casting. Thus, a casting number will always be raised above the surrounding surface.
A forging number is beat (pressed) into the metal being formed into a crankshaft sometime during the forging process and thus will nearly always be indented into the surface.
Let's keep the facts straight. Talking about casting numbers insults a forged crank.
R. Then maybe this is one of those rare forged cranks that has a "number" raised above the surrounding surface, instead of indented. Like a casting would.

Semantics. Valve covers would more accurately be called rocker arm covers. A Xerox copy may not have ever been near a Xerox manufactured machine.
I understand that the numbers on a forging are not literally "casting" numbers, however, they're called casting numbers on more reference sites than not.
In the future I'll try to be more anal when I ask questions.

Don't ever say frame off around here or kitten will be shat out at prodigious rates.
Even if it's a truck
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Didn't early big blocks have an extended flange? I think pre 62.

Those are little before my time so how did the crank connect to the flywheel/ flexplate without threads? Through bolts with nuts? Yes, same as the old flatheads did. Not sure why they thought that was a good idea back then,

Not sure why they thought that was a good idea back then, I'm guessing so you could check the torque converter/flywheel attachment nut torque without disassembling the whole assembly. Same kind of thinking that led to left hand lugnuts.

Didn't early big blocks have an extended flange? I think pre 62. Your correct on that, 1962 was the first year of all aluminum one piece BB 727 front case with the shorter crankshafts that had the threaded flanges that use bolts to hold the flex plate or flywheels to the crankshaft along with the converter flywheel alignment ring around the center of the crankshafts to align the flywheel s or flex plates, they didn't fit over the outside diameter of the rear crankshaft flanges like the pre 1962 motor used The all aluminum case 727 1962 in Dodges and Plymouths and later cars were way better designed and lasted a lot longer with hard abuse than the 1961 and earlier cast iron torque Flyte did: up:
