It begs to be revved.

While Renault later introduced thinner, lighter blocks for cost savings (the F817 series), the DF084 was built when steel was cheap and engineers worried about torque. This block can handle a surprising amount of abuse, overheating, and high-hour wear before cracking. Renault no longer supports the DF084 directly (they
