Re: Rod and Main torque specs
Are we talking stock or aftermarket hardware? studs or bolts? what type of assembly oil used? couple things that should also be noted.

Re: Rod and Main torque specs
Yes it is all stock. To this point I have been using msall block 2-bolt main specs. 80 on the mains and 45 on the rods. Havent had probs yet. I am having trouble wiht one rod cap. It somehow got mixed up with another one cause when I torque it down the crank bearly moves. I havent had time to figure out where its rightful home is yet but will mess with tonight. Atfirst I thought I was using the wrong torque specs but then realized it was the cap itself. I may have to put this thing in storage for a while and may have to have the motor totally redone. .
