392 Flywheel on a 331 Hemi
 

Does anyone out there know if a 392 flywheel will work on a 331 hemi (extended bell)? I currently have a PowerFlite setup & would really like a third pedal in the cdan's future. Thanks.

CHECK THE BOLT PATTERN ON THE CRANK, DOESN'T LOOK THE SAME TO ME.

Oops, sorry didn't mean to yell.

This is the bolt pattern on a 331 and I think 392 also.
check the offset on the two holes at the bottom of photo.

I think it is the same bolt pattern that MOPAR has used on EVERYTHING since the creation of DIRT.........

I have been looking through Ceridono's book & the only passage I can find is ' ... stock hemi flywheels from '51-'58 mounted to the crankshaft with eight bolts & registered on the outside diameter of the crankshaft flange ... ' A 426 flywheel needs mods as it registers differently on the crank. Unfortunately I cannot get access to the crank any time soon ... distant storage & another tranny (Powerflite) is hooked on the end http://www.jalopyjournal.com/ubbthre...lins/crazy.gif

Then again HotHeads lists the following flywheels ..

Chrysler Flywheel - Aluminum - 13# '51 - '56
Chrysler Flywheel - Aluminum _ 13# '57 - '59

Thanks again for the responses.

This be a 331 bored out 20 thousands. Its a 55 and that crank adapter was made for it. That is what your crank looks like.

if you still can't get a look at your 331 crank and still need to know the bolt pattern, I can take a rubbing off the back of mine, [53 with extended block] scan it and e-mail it to ya..Let me know via e-mail.
Gotta love electronic technology.

BTW, every hemi book I have says chrysler/dodge never put a manual tranny behind a 392 Hemi. May I assume you're working with an automatic?
I'm using a poly-head dodge truck stick flywheel [thanks again, Silent Rick] behind my 331. Seems to work ok but I don't have everything assembled yet.

Interesting point ... the closest manual trans might be the Fluidmatic auto/manual trans that everyone dislikes.

Further fuel ...

My experiece is that every thing interchanges. I have used the 6 hole and the 8 hole flywheels. I think the 6 hole ones came from the FH 6's. I have used them on the Dodges and the Chryslers. I prefer the 6 hole ones due to their lighter weight. Some of the 6 hole ones came with odd ring geares but the ring gears from the Powerflight auto's can be removed and substituted onto the flywheel. http://www.jalopyjournal.com/ubbthre...lins/smile.gif
