Venolia domed piston info
Friend just picked up a 64 GTO with a 72 455, 7L4 heads, unknown HFT cam. It ran ok but he is going through the whole car. We pulled the heads off today and found the pistons were dome type Venolia. Only part number visible was 400B. Dome sticks up about .100 from deck. Obviously dome was picked to raise compression on the 7L4 heads. The plan was to put a set of #96 heads on and new cam, then seal it up for a quick, budget upgrade. First question, anyone know the dome cc on these? Venolia is out of business so I cannot find info online so far. Second question, any worry about clearance with #96 head? Once I know dome cc, I can calculate compression ratio of course.
