Having familiarity with the 4.6L Lincoln/Ford "Modular" engine (and OD trans). i have to figure the OHC as a feature since it has been trouble-free on 4-5 used vehicles i've owned. What ever happened with 5.4-5.7-series engines with Cam Phasor KNOCK brings grief with any notion to "go bigger".
Any engine using cam and lifters seems to have a common wear-to-failure mode there. If the LS engines have Roller Lifters, then what keeps us PMD folks from fitting them in our Pontiacs?
Is there an OHC LS?
