the stock intake pull seen here was at its opimal tune,
the black thingee under the carb is 3/8 spread bore spacer with 4150 sealing gasket was used under the square bore Edelbrock carb as it arrived to me.

While I don't doubt the aluminum intake has the ability to make more power, I can't help but wonder if the square bore carb adapted onto the spread bore iron intake may have hurt it's power to some extent?
