well thanks for the kind words Al. Sounds like you have quite the power plant under the hood. That's some ponys there. I know an engine builder near me that put together a 409 chevy BB with 2 500 edelbrocks and it ran real good on the dyno.It went into a 61 or 62 bubble top impala. I think that motor n/a made in the mid 550hp range. He liked edelbrocks for dual applications.
