This coming weekend I am going to replace the upper and lower intakes, heads, cam, water pump etc.. on my 93 LX Mustang (SSP). The car has 155,000 on it. Thus far I have added 3.73's, headers, BBK Cold-Air kit, Aluminum driveshaft, MSD Dist. Cap, Auto plugs and FRP 9MM Plug wires. I am getting mixed feelings on how to proceed after every local Mustang enthusiast has given me their two cents. Honestly I'm scared to death, this car is my baby, I have waited my whole freaking adult life for this exact car, it's beautiful and I want to keep it that way, runs great no smoke etc. My question is this, with the addition of a Holley Sytem Max upper and lower, perfomer heads with roller rockers,a Trick Flow Stage I cam, and a BBK fuel pressure regulator do I have anything to worry about on the bottom end. I don't plan to run the car super hard (no drag racing), I just want a good sounding, solid running car, head turning car. One person said I should take the motor out and check the pistons, bearings and rings. My friend who is helping me knows mustangs in and out and has numerous years of experience with Mustang drag cars and Mustang street cars and he said there's no reason to do all of that. I am at a crossroads, what do I do, I have no reason to think I should do anything to the bottom end, but I'm new to this. Any and all opinions are welocomed. Thanks for the time and help!!
