Ok, my car is actually not a mustang, it is a 91 cougar, but it has a 5.0 in it, so hopefully someone here can help. The motor is out of a 95 mustang GT and I swapped in a B-303 cam and GT-40 heads, bypassed the smog pump, and deleted all the A/C stuff. Here is the problem. There is a ticking noise that sounds like it is coming from under the passenger side valve cover, and the car is seriously down on power. Also the oil pressure is kind of low when idling (15psi in gear, 20psi in neutral) but comes right back up as soon as I get on the gas. I clocked my 0-60 yesterday with a stopwatch, and it was about 10 seconds. Considering it was 8.1 when the car was completely stock with 200,000 miles on it, it should be much faster than it is. Also the car is not producing a lot of vacuum. It gets about 10" at idle out of gear, and about 5" stopped in gear. I don't know what the bcam is supposed to pull vacuum-wise, but I get the feeling it should be more than that. Anyone have any idea what is wrong with my car? Thanks.
