Flywheel Bolts, How much clearance needed? #1391846 02/21/13 10:51 PM 02/21/13 10:51 PM

I noticed that the bolts protrude through the back of the crank a little, maybe 2 or 3 threads and come very close to the back of the block. The clearance is a little more than a sheet of paper. Is that normal? If not, is it safe to use grade 8 washers with the bolts to compensate? 1968 Coronet 1968 Charger 1966 A100 Pickup 1967 Barracuda 1970 Challenger 1972 Challenger 1973 Barracuda 2021 Ram 2500

Just grind a thread or two off (carefully) clean up with a die and sleep well

If not, why not the thin(.060 or so) harden head bolt washers will keep the heads of the bolts from eating into the flywheel Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

Just figured that was the way it was supposed to be. 1968 Coronet 1968 Charger 1966 A100 Pickup 1967 Barracuda 1970 Challenger 1972 Challenger 1973 Barracuda 2021 Ram 2500

Just figured that was the way it was supposed to be. that is correct, they are designed to be used as is & they have a machined surface on the underside of the head. trim em as is if you can get to the ends & if not remove them & trim them then reinstall/torque with loctite live every 24 hour block of time like it's your last day on earth
