Just want to verfify the oil pump mounting bolt torque specification. My Helms manual has two different torque values -- the one on page 6A3B-36 states "Oil pump bolt/screw to 66 lb ft", but in the torque specifications on page 6A3B-43 it lists "Oil pump bolt/screw to 66 lb in". WTF?

I torqued it to 66 lb in, which is probably wrong. Looking at the Haynes manual, it shows 65 lb ft. Would someone be so kind to let me know what the CORRECT torque specification is? Does using an ARP stud make a difference in the torque spec?

And I just got the engine back in too!

It's 65 foot/pounds of torque. What you did will definately not cut it.

Both listings do say 90 Nm and that is 66 lb. ft. The lb. in. can't be the right one-too loose.

The bolt you use should not make a difference in the required torque value.

I never pay any attention to the Nm value, and when I installed it, all I did was look at the specifications page. I thought it seemed really low, but what do I know?

Figures too -- I have to take off the Y-pipe and I'm sure I won't be able to get the Canton oil pan off even though I have BMR K-member. Ugh. Guess I'll just drop the motor again. Good thing I didn't get the rest of the front end put together (the tranny is still out too which will make it easier).

Oh well, it'll allow me to go ahead and install the new wires while I'm at it
