I'm about to start my 5.0 crate motor for the first time in a few weeks. It has been converted from EFI/TFI to carburated, mechanical fuel pump and MSD Billet Distributor ignition. It all fits fine but I still have a nagging question as far as oil pump drive. A hardened SVO piece has been installed along with a Melling HV oil pump and pickup.
I am aware that the 5.0 original distributor has a longer body casting, ( I sold the one that came on the motor w/o checking) but have not been able to determine if I need a different length drive for the pump. I have .500 +/- engagement in the distributor. It will run that way - I just want to make sure it keeps running !!! Has anyone checked this out?
