Default Re: Aftermarket Cranks

When you grind a 3.980 FE crank to 2.200 the crank is lighten about 1.625 pounds. I said pounds not ounces. The big gain is the change in polar moment of inertia. The weight reduction and where it occured is a big reason why the engine will accelerate faster. Multiply that times three if an automatic and four if its a stick and Ta-dah the car is faster.

And why does the 390/ 427get to use these rods?
