My first post so don't be to soft on me. This is what I've added to my 94 Mustang GT stock block with 92K miles: Trick Flow H/C/I, Vortech S-trim, 75mm Throttle Body, BBK headers/shortpipe/Flowmaster 2.5 in exhaust, 3:73 Gears, Trac-loc differential, Anderson Powerpipe, 42 lbs injectors with calibrated MAF, Smog Pump delete, Aluminum driveshaft, Mitshimoto Alum Radiator, SCT custom Tune. It's been professionally dyno'd and the result was 440 RWHP and 432 ftlbs of torque. I'm not looking to add anything else because it runs good and I don't take it to the track. It's just fun to drive. Should I be looking to buy a stronger block soon or am I ok for a while? I've read a lot of the splitting the block stories and I'm not sure if it was a result of racing or just driving down the road.
