The tranny mounting is the same as the RWD models. The only thing that I know is different is the cooling system outlet that connects to the lower radiator hose. It's a little longer with an extra bend and has 2 1/2" hose outlets.
I thought one of the neat things about the 310/F10's is the way you can change out the clutch in about 20 minutes! A couple of bolts and the clutch pilot shaft comes out the end. Remove a tin cover and you can remove the presure plate bolts. Lift out the presure plate and clutch disk!
Don't try to make a high performance clutch by stacking 2 of the diaphram springs on the presure plate. A friend tried that. Not sure what was happening, maybe the stacked springs were bottoming out but it wasted the center main bearing's thrust washers.
The stock clutch seems to be hard on the thrust washers as is. I have used a couple of engines from 310's and in both of them the crank had lots of end float. The one we put in the race car had almost 1/8" of float! It was for a trailered autocross car so we just used it as was. Never blew up!
