Hi all! This is my first post on this forum and I am hoping for some help. I recently took the 302 out of my 69 mustang and stroked it to a 347. It is bored .030 over and I used an eagle kit to stroke it to 347. I took the entire assembly to the machine shop with my flywheel and harmonic balancer (fluidampr) to get balanced. I assembled the block and also installed an Edelbrock Pro flo 4 efi system. I want to be able to drive it all the time but have some bad vibration and I think its coming from the motor. The motor mounts are not new but they are adjustable so I can move the motor forward or back to line everything up. The mounts were not rotted or cracked in any way. I do have the alternator, power steering and ac hooked up with under drive pulleys. At this point I am so frustrated I keep second guessing everything that needs to be done and really don't want to rip the motor out again. If you need any other info please let me know and PLEASE HELP!
