i just found the easy way to turn a flywheel.i recently put a 435 4 speed in my 150 with a 440. the bellhousing is small block so i made adpter plate. i didn't surface the fly wheel.for 600 or so miles it would shudder taking off, not slipping in smooth. i was worried of the torque tearing the truck up so have been taking it easy. well saturday with lots of attitude i finally found out what its got. i got into 3rd smoking my 33's before theye grabbed. since thanthe cluch has been good and smooth.it will slipp if i dump it in 3rd standing still,but only than.those 440's shure have some [Edited by Moparts - Keep it clean].
