Hello everybody.

A friend need to find these bolts but don't have the way to find.
Do you know about 340 block to 727 torqueflight bellhousing bolts?

I've find two references at summitracing but there's two different sizes. And I'm not sure about both.

Bellhousing Bolts, Allen Head, 7/16-14 in., 1.250 Underhead Length, Steel, Set of 6

or

Bellhousing Bolts, Allen/Hex Head, 3/8-16 in., 1.500 Underhead Length, Steel, Set of 6

Thanks!

I think they are the 7/16ths size. Pretty sure they are on the big block anyway. Wish i had a 340 handy to check for you.

3/8 - 16" on the small blocks & in some cases, the intake manifold bolts are exactly the same, right down to the head stamp.
