Exhaust Stud Question

[Storming Heaven]

does anyone know what the exhaust stud size is on the 4.0? mine is missing on the lower #6. i'm hoping that it's just missing and not broken.

Listed as .375-16/.375-24x1.75 for the two in the head.

I just installed a 00' intake and new header and I replaced all the fasteners with stainless hardware, the bolts were 3/8"-16x1-3/4"(9) and nuts/studs were 3/8"-24(2)

This was a Great Find ! If pierceME311 is still around, or anyone else know ... what is LENGTH of Studs required ?

Really surprised that it wasn't metric, since so many other bits are ....

Looks like MJR already posted 1.75"

Everything that connects directly to the head or block of the 4.0 is inches.

Doh ! I missed that 1.75 ....

This piece of information is so helpful right now. Yes I'm bumping an old thread just to show I searched. :moon:

impressive. I think when I start getting to $115 manifold studs I start looking into swapping engines.
