I am going to upgrade my 2 piece rear main seal 5.7 to a newer 1 piece.

I have the Gen 1 outdrive, will it mount to the newer coupler? I am already going to have to get a new flywheel starter and coupler, id like to keep the outdrive, is it possible, it sure looks the same?

Repowering with a newer block should not be an issue. What year is the original motor?

 

[dan2744]

1985, this one is a 90 s block with 1 PC seal. What flywheel do I need?

 

[alldodge]

Assuming pre-vortec
If your old motor has a 12 3/5 flywheel, you will need to get a 14 inch flywheel and bell housing. Need the triangle coupler and offset starter

That's what I was thinking just wasn't sure about flywheel, thanks. It is pre vortec.

Will the older Bell housing work for this?

Will the older Bell housing work for this?

Lets ask Bondo

 

[dan2744]

It looks the same, I know I need it for the mounts but I haven't pulled the motor yet

 

[alldodge]

It does list the same part number clear through from what I found

That's what I'm seeing also, thanks.
