Cast Cranks - How Much HP & RPM?

[Rory428]

In my 428 powered Fairmont drag car (bracket racer), I`ve been running a stock 428 1U crank for 10 years now, with zero problems. It`s a 4 speed, and I dump the clutch between 6200-6600 RPM, shift at 6200, and hit 6500-6600 at the finish line. This engine has never been on a dyno, but according to my trusty Power/Speed calculator, it should be around 550 HP. I recently had to junk the block, as it split the #2 &4 main webs, but the crank looks ready for more! I have raced FE`s for almost 30 years now, and the only crank failure I had was years ago with a 390 on nitrous oxide. This engine was also in my Fairmont, and ran similar numbers (10.2 Et @ 132 mph) with a C6, and after a couple of years, the block had ALL the main webbing rip out between the cam & crank, which broke the crank in 5 seperate pieces. But other than that, the stock cast cranks have held up very well for me. In fact, other than splitting a couple of cylinder walls on 428`s, the one split main web on the 428, plus a couple of broken OE rods, the FE has been pretty darn reliable for me.
