How long do I roast a 9 lb leg of lamb med to well done and at what temperature

it all depend how you want your Beef

Rare:

• 120-130 °F (50-55 °C) Internal appearance very red; very moist with warm juices. Approximate cooking and resting time: 20-25 min./lb. plus 8-10 min. resting

Medium-rare:

• 130-140 °F (55-60 °C) Internal appearance lighter red; very moist with warm juices. Approximate cooking and resting time: 25-30 min./lb.. plus 8-10 min. resting

Medium (with a touch of pink):

• 140-150 °F (60-65 °C) Internal appearance pink red color; moist with clear pink juice. Approximate cooking and resting time: 30-35 min./lb. plus 8-10 min. resting

Well-done:

• 150-165 °F (65-75 °C) Internal appearance no pink or red, slightly moist with clear juices

Divide 500 by 40, then multiply 1 to 2 by that number.

Here are the cylinder head torque specs for Chrysler Town And Country 3.3l:
You will find a tightening sequence in the cylinder head bolt location-tighten the head bolts 1 to 8 accordingly using the four-step torque turn method
Here are the steps:
1. Bolts 1 - 8 to 61 N•m (45 ft-lb)
2. Bolts 1 - 8 to 88 N•m (65 ft-lb)
3. Bolts 1 - 8 (again) to 88 N•m (65 ft-lb)
4. Bolts 1 - 8 turn an additional 1/4 Turn, this step does not require you to use a torque wrench
Remember, after 1/4 turn, the bolt torque should be over 122 N•m (90 ft-lb). Otherwise, buy new bolts. Once all that is done, tighten head bolt number 9 Cylinder Head Bolts Location and use Tightening Sequence to 33 N•m (25 ft-lb)

Commonly Asked Torque Specs in foot pounds
The main bolts have a torque of 76 lb.-feet and the cylinder head bolts have 62 lb.-feet of torque. The cylinder head studs have 70 foot-lbs of torque, the cam timing gear have lb.-feet of torque, and the cam bearing bolt has 14 lb.-feet of torque.

Crankshaft Torque Specs

• The stock rod bolts have 46 lb.-feet of torque and the ARP rod bolts have 50 lb.-feet of torque. The crankshaft pulley has 116 lb.-feet of torque, while the flywheel has 80 lb.-feet of torque.
  

Other Torque Specs

• The intake manifold and exhaust manifold have 33 lb.-feet of torque each and the oil pan bolts have 9 lb.-feet of torque. The cam timing gear has 58 lb.-feet of torque and the cam bearing bolt has 14 lb.-feet of torque. One set of timing cover bolts have 9 lb.-feet of torque and another set has 29 lb.-feet of torque
  

for the 2.2L OHV:
(pully 8 4 1 5 9 <-- long bolts @ 63Nm (46ft/lb)
side ) 7 3 2 6 10 <-- short bolts / 10 is the stud @ 58Nm (43ft/lb)

for the 2.4l dohc are as follows:
(pully 9 3 1 5 7
side) 10 6 2 4 8
bolts 1-8 torqued to 65Nm (40ft/lb)
bolts 9-10 torqued to 40Nm (30ft/lb)

then (either engine) give each an additional 90° (¼) turn

it's best to do the tightening in stages, you don't want to go completely tight on the first pass or there will problems and you'll get to do it all over again

2.2 4 cyl. ?

8mm bolts are 16 ft-lb, 6mm bolts are 9 ft-lb. Tighten them a couple turns at a time. A service manual will have a diagram for proper tightening sequence.
