Nascar con. rod bolt torque spec.

[RICK LAKE]

A first name would be nice. Anyway I have a set of c9zz6200a rods in the boxes in my basement. I was going to use them in my first Shelby motor with a 428 crank, 10-10. RPM limit 6250. Eagle had just came out with there new rods and on sale. The eagle rods where 100 grams lighter and for a 2705 lbs ERA cobra and low rpm limit, it was a no brainer for me. I also got the ARP rod bolts for these rods. When Charlie balanced the whole assembly no wieght was needed. I would not spin these eagle rods to 7000 rpm or take a chance with a NOS 427 block. I would go with the 3.98 crank. Barry R. sell a nice kit that drops in. Just get it balanced and tell him the flywheel wieght and balancer wieght. I run a 20 lb flywheel not the 40 lbs that came stock. I am building #2 motor and have gone the bigger path with a shelby motor, a 496 but small bore and long stroke. I am going with a set of Howard BBC rods that are 796 grams each, a balanced set, was told they are good for 1k hp. I am looking for 600 hp and 650 tork when done. RPM limit 6500. 3.31 gears may be too much for the car. may drop to 3.07s. Try and stay light and strong with parts, match the intake,heads and camshaft to work together. Look at the drivability for cruising. Big cams are a pain and need more maintainance than smaller ones. Talk to the Smith boys about engines sizes and max controlable power for your car. I don't have the biggest motor or strongest and after 6 years of R&G I broke a rocker shaft finally. The clutch is the only problem I have had. Maintainance basic, Fun and down time little, time with car priceless. I help others fix there cars. Rick Lake
