I recently bought a 396 sbc stroker from a buddy. He had it built put it in a drag car made a few passes with it and lost interest.
I am am in the process of freshing it up, changing the cam and a few other things so I can put it in my aluminum jetboat. He said it always wanted to blow out intake gaskets so he put breathers in the valve covers with lines running to the exhaust to remove the pressure. I don't want to do this on a boat.
What are my options, no pcv, will a catch can work? Or do I need to get a vacuum pump?
