Running a two piece rear main seal crank in a 1 piece rear main seal block The tile pretty much says it, what all is required to convert to a two piece rear main seal crank from 1 piece? My understanding is that I will have to: Get a seal converter/assembly (bolt on, no machining required?) Get a neutral balanced flywheel/flex-plate to replace the one piece one I currently have. And thats it? That seems too easy... |
Re: Running a two piece rear main seal crank in a 1 piece rear main seal block Why would you want to downgrade to the two piece main seal? |
Re: Running a two piece rear main seal crank in a 1 piece rear main seal block most high end cranks are designed for a 2 piece, so to run the crank I want I need to It also lets you run a neutral balance flywheel |

As mentioned you can get the rear seal adaptor for either for either the early pan or the late pan, I prefer the late pan as you can use the one piece oil pan gasket from GM = no leaks. Also you will need an alignment mandrel to locate the seal adaptor. http://i7.photobucket.com/albums/y27...ockwork004.jpg |

Re: Running a two piece rear main seal crank in a 1 piece rear main seal block You want the later 1-piece rear seal block because the machining is much more accurate than any 70's block. Not that a 70's block can't be corrected by a very competent machine shop, but you will pay dearly for that. The better choice then is a DART block. |
