Jim, I run a windsor stroker motor. External fluid type harmonic balancer does well on mine past 7k R-S. Now on to the main seal. No need to pull the tranny. Drop the pan , loosen the rear cap insert the two piece velcro seal and offset it. My engine was pouring
oil at 1000 miles. The problem is this on strokers. Man they have to breathe big time!. One vlave cover has to breathe and the other exhaust. Keep in mind if your are running PCV that on acceleration (floored) that the engine is only breathing out of one side. I run K@N breather on intake and an
oil collecting breather on the other side dumping into a remote collector /breather. High compression stroker motors do not like crankcase
oil mist comming through the intake. That is my story and I am sticking to it. C-Man
