I have a 92 ford mustang shell and want to put in a 4.0 V6 engine. can it be done?
YES - but if your gonna replace with a 4.0 V/6, try to find the S.O.H.C. version. Will feel more like a V/8 than standard 4.0. Will not have any problems with installation, with just usual suspension, cooling and wiring upgrades.
