I used the same flywheel off of my 351 on this late model 302 injected motor which I put a carb on. I am wondering about my tech advice as it has a shake/vibration to it between 600 and 1500 rpm. I have cycled through every vacuum and ignition possibility (I wont list all but I am experienced in basic induction and ignition stuff). I am left pondering if I need to change balancer and or flywheel. HELP! This truck is so close to being right and it sounds great. It just has a vibration at low speed like a counterweight issue.
Basically I took the 351 out of my 83 F250 and had a deal on this 88ish 302 injected motor out of a Crown Vic. Yes, Im wishing I would have just rebuilt the 351 but....oh well.
