Engine bolt specs

[spitfiremk1guy]

I have a long block and transmission that I need to attach together for transport, but I don’t have any of the bolts. Does anyone know the length, size, and thread pattern for the bolts to secure the transmission to the engine?

Thanks,
Andrew Moreau

Andrew,

Gearbox to engine block: 7 x 5/16″ UNC. x 1 and 3/8 and 4 5/16 UNF x 1 and 1/4″ inches. There are also 4 plain nuts of 5/16″ UNF.

I would doubt you need the 4 nuts
