iam looking at getting an 86 gt stang, and my brother in law has an old '89 crown vic with a 351, and i was wondering if this is a decent engine? i had planned on putting the gt40P heads on, with a lightning lower intake, with a explorer upper, (or a whole lightning upper and lower) any way, i had a friend at autozone, pull a lifter for the car, and it is not HYD roller, and i was wondering what it would take to convert it to hyd roller? iam not very familliar with fords.... oh yeah one other thing, is the '86 hyd roller?
