they came off 350/270 motor.I figured id could mount them backwards,then attach pipe,to curve up,and out the back or over the transom.I seen guy do it on 351 motor,but his looked wierd,any thoughts on how i could make them work?they would go on checkmate boat.If i could make these work,doesn't two holes have to be drilled too for the water to exit in different places.for the price of 250 witch these are,i would never find stainless,or chrome manifolds,plus i like different.Maybe someone can engineer idea,or just tell me to forget it.

Anything can be done if you got deep pockets!
That looks like it could be expensive.
Does it have any other fittings?
