Wrong, the OHV 4.0 is tough but it has very little that the SOHC 4.0 doesn't have. That very little is; 4 (or less) lb-ft more torque at rpms under 1500. That is less than 2% difference. Otherwise, the SOHC is superior in performance. Durability of the SOHC 4.0 seems to be good but the added complexity of the cam drive leave it suspect to failure before the OHV.
