Just an FYI for anybody else considering going this route. An Explorer 302 and it's accessories look to clear with plenty of room.
I bought that little 302 about 2 years ago for a song. I thought about piecing together Fox or SN95 accessories... mainly because I didn't know if the explorer brackets and stuff would fit inside the engine bay. I was worried about that lower idler pulley, and the height of the PS pump and alternator. In the end, I decided to just do it as is.. and if I had to change it all .. so be it. Today.. dropped in the motor and trans for the first time. And.. to my pleasant surprise... plenty of room. I'm still not sure about the PS reservoir, but the rest has plenty of room. It's worth also noting, I'm using solid motor mounts that have a 3/4" drop over stock. Also.. there is a 1/2" spacer between the intake and carb.
