Big Block Edelbrock limitations.

We just finished a 440, that has the 516 heads with oversized valves NO port work, flat top pistons and just .525 lift cam, that ran 11.11 and 120 in a Duster street strip car, your will not need a stroker motor to run mid 11s

Surely you did some bowl work. otherwise increasing the valve size had an adverse affect on the 516.
