Jay... Those of us that know your car, realize it deserves a lot of TLC from you.
Please don't think this is bashing, merely informing newer members so they are not afraid to mod because of you saying how once you started modding your car went downhill.
Whenever beginning to mod a car, all normal maintenance and preventative maintenance items should be up to snuff. Over 20,000 miles on an oil change makes your last motor the trooper of the century in my book. Your struts were nonexistant as far as I could tell. I believe we are aware your car needed a couple of things when you began modding.
A harmonic balancer controls timing etc and will cause many issues. Get it fixed..then see how the car reacts.
