"I am thinking of replacing my 1986 omc 4.3 exhaust manifolds. Does anyone know if you could use Volvo 4.3 manifolds. Isn't the 4.3 a GM in both omc and volvo/penta? I would have to make up some of the pipe from the Volvo riser to the omc transom pipe, but $200 per side for volvo 4.3 manifold/riser vs. $1000 for omc (if you can find) seems tempting. Any thoughts?"
