L31 with mechanical clutch
Do the new L31 crate engines come drilled and tapped for the clutch cross shaft ball stud?
Thanks! Posted via Mobile Device |

Re: L31 with mechanical clutch
my 4 bolt main l31 has a hole drilled / tapped just above the oil pressure port above the filter boss area .
the hole goes in to the bell housing cavity . i think its the right one for mech clutch ? ?

Re: L31 with mechanical clutch
It depends on what year truck you are installing the engine in. The '63-'66 trucks require the forward boss for the ball stud for the bellcrank.

Re: L31 with mechanical clutch
My L31 was a take out from a 99 model and accepted a mechanical clutch in my 78 no problem. But I'm pretty sure it attached to the bellhousing not the engine. Been a while so I forget lol.

Re: L31 with mechanical clutch
Yes the square bodies have the clutch ballstud bolted to the side of the bellhousing.
