Mercruiser 431-811658 specs:
196/206 duration @ 0.050"
.431/.451 lift. 109LSA

Im looking for a take out if anyone has a stocker laying around.
I have everything else. Had to help dear ole dad out and gave him my spare.
I’m converting a 305 over to roller (factory roller block) for a Bottom Liner cruiser we have so nothing special and staying on a cheap budget,

Or something close to the above grind. Factory or slightly above is fine.
Im in Maryland eastern shore side and found one in Jersey but guy doesn’t want to ship.

Thanks everyone
