I have an 86 GT EFI with 52000 original miles on it. I took it to 4 different shops and they all told me there was a noise down bottom and I need a new or rebuilt engine. I have little money at best and cannot do the engine swap myself. It seems by most internet accounts that it is cheaper to buy a crate instead of rebuild mine. I don't want to use a junk yard engine cause its not worth the risk since I will not be doing the labor. So here is where I'm at, it will be a drive around town car. I want it to be able to do 2 or 3 hr. trips one way. I want it to be fast and I have delusions that I will put a super charger on it at a later time (probably never happen). I know fast is a relative term, so for this discussion it means able to run with cars of today on the street. I basically want the speed and reliability of a new mustang with my style. I'm not to familiar with the way heads and cams work as far as numbers porting and such so please keep it basic. How much horse power do I need to get to where I want to be? I'm in NJ so any local knowledge will help.
