[95BlackJack]

Ok so first car info: 95 Mustang GT. 5.0, 5 speed manual
Known mods: BBK Shorties, hollow cats, cherry bomb incinerator cat back, MSD wires, Mild Cam (?)
Bought the car with these mods in it and i'm having some tuning issues.
IS there a cam that someone might use that gives all low and mid range power but loss at high rpm? (above 4,000).
i have a ton of power and pull between about 2,800 rpm and 3,500. Timing is set about 13 degrees advanced. It starts kinda hard, just lugs over a few times before starting up. If i retard the timing, i get misfire above 3,500 rpm real bad and the SES light comes on for a rich condition about 10 times a day. If I Advance the timing more, i get awesome power above 3,500 rpm, all the way to 6K. It will smack me back in the seat and take off, but it will also spark knock like hell that advanced and hardly starts at all when it's hot.

Any ideas here??? I've also noticed car is running hot. Distributor is brand new from auto zone, OEM Spec. Coil looks factory and old. plugs are so-so in it right now.
is it possible my cam to crank timing might be off by like 1 tooth?
Somebody help! I'm tired of trying to fix this and feeling like shooting at the stars instead....

I would replace the coil and wires before anything. Your old coil and wires may not provide enough spark at the higher RPM's and may be the cause of the hard starting issue.

i've been thinking coil now for a little while. the wires are brand new 8.8's, and the plugs look questionable....
