Need some help

[Fatality51]

Got my engine back in my car but somehow the bell housing bolts are MIA. Anyone know what size / thread bolts I need? Can't find them anywhere. 1963 marauder

Seriously not one person knows?

here you go

should be close to this size

I bought those bolts today from a hardware store and they are way to short. I'll try a longer bolt and see if that does the trick

Been too many years since I did work on my FE block

Nevermind did not realize this was in the classic forum.

Well it's kinda complicated cause I guess in 64 they started using the "C" transmissions and prior to that they were merc o matic so I think the bolts are different. I'm just gonna buy longer bolts and hope that works.

You have to know whether they are sheer strength, or tensile strength, in this application, I would say they are sheer strength, because of the torque of the engine, but may also be tensile, do not buy bolts from the hardware store, unless they are graded to the application.

I believe they are 7/16-14

7/16 2 1/2 coarse bolts grade 8 did the trick

Glad to hear you got it resolved.
