Going to look at a 409 for sale....posted previously.......and found out it was taken out of a boat....running reverse rotation..
This is what I have learned about marine engines;
They rust from the inside out.....so we need to pull the frost plugs to look for FeO2...
The crank is not suitable for standard rotation....as the rear main seal journal has reverse grooves cut in it for oil control...
Camshaft,timing gears/chain,oil pan,exhaust manifolds,carb and intake are prolly NOT suitable for a car installation..
Seller says that pistons pin holes are concentric...and NOT offset.....is this the case with ALL 409 pistons?
I stand to be corrected on info I posted ....and if anybody has anything to add....please DO.
