216 crank swap

heres something for the big brains of the HAMBS. i cant seem to find the 4 bolt 216 flywheel that im looking for so my question to you guys is if i can swap the cranks from a 39 216 and a 46 216 so that i can use the original 6 bolt flywheel without having any problems. in my eyes i dont see why this wouldnt work since they are both 216's. am i wrong? if i am please let me know before i get myself into something that might end up beign a complete waste of time. thanks

 

I used a 37 crank in my 42 block....no issues

 

so then i should probably just do it and stop playing the treasure hunt game looking for this flywheel huh.

 

I don't understand the flywheel thing though. Both the 37 and the 42 were 6-bolt's....

 

no ive done some research and found out that in 1941 they changed to the 6 bolt. the previous years had the 4 bolt. also the heads change to a smaller plug for a few years before they go back to a bigger plug. this was told to me by a 70 year old timer that i use to work with at kragen that still works there. i havent had a chance to go back and ask him about the cranks. its crazy.

 

My 37' engine may have had a newer crank in it then. With that said, I may be full of it!

I think the small plug thing was around the 37' mark as well. I have one in my gargae from that same engine.

 

i would ak these guys www.chevytalk.com and www.stovebolt.com post your answers that you get. post some pic's of your project.

 

Chevy sixes had what we used to call "peanut plugs" up to/through about '48 on p***enger cars IIRC...............don't know about the trucks......but why not them too??
