399 CCW engine

[Ivan]

I am going to put new crank seals in my 399 engine. Can I do this without taking the engine apart? Is it easier to do if I take the engine out of the sled? Thanks Ivan

The seals can be installed without a tear-down. Yes, it is much easier to remove and work on the engine on the bench.

I would take it out and reseal the crankcase while your at it....just my $.02!
