Not sure if this is the right place to ask but I'm running into a very strange issue now. With everything going on I haven't driven much since the swap, only a couple weeks going to the office. Since it's been sitting something must have happened... I was driving heading to the highway and felt some light shuddering. The car was shaking (kinda felt like when you're braking and a rotor is warped). The shuddering got worse on the highway literally shaking the dash (again, like a warped rotor but very intense). I got off the highway and pulled over. In park I sat there and gave it some gas and there was the same shuddering, put it in neutral and same thing. So that eliminates the brakes, suspension, driveshaft from making the vibrations. I'm a bit paranoid and expecting the worst, thinking it might be something with my converter, the vibrations change with RPM. The engine is very healthy and not making any weird noises, I also gave it an oil change today and it looked fine (also had Lito look over a log, checked out fine). I did a bolt check on pretty much everything. I have a 6 bolt crank, SFI hughes flexplate, circle d 3b 258mm converter, ARP flexplate and converter bolts, 6r80 from a 2wd 5.0 F150. Any ideas?
