call someone (krane, comp who ever) but an aftermarket cam install is not a simple drop and go, they need dialed in, cyl head needs removed to degree the cam in, you have to know what your doing with this one, and in a 95, your only real option is a 4x4 or rv styled camshaft, but a cam for a 4.3 is EXPENCIVE (unless you call epc and have them cut you one from your specs) you seam smart, you wanted specs, i mentioned more then i felt needed for you because people can look this up and i dont want someone to think they buy a cam slap it in and go, and also a wild cam on a computer injected moter will need a chip cut, cost is around 410 dollers (thats what it was on my 88 firbird, blew the 2.8 and put a 3.4 block in it with the 2.8 injection) you have a newer computer, possibly a obd II possibly an obdI, so it could be more then that for a cut chip
