Offy Portasonic big block intake
This is an Offy Portasonic intake that has been welded on the top of the intake runners so it could be ported to raise the top of the runners . The intake port sizes are 1.300 wide and 2.600 tall . You would have to port your heads to match these . $ 250 plus shipping from zip 60034 .
