I was thinking about these and thet Holley of back in the day.
And about the same time frame Holley made one. Short Small Ports, and had a balance tube from side to side.
FYI Back then I ran a Street Dominator and 650 DP and got (SPG) Smiles Per Gallon instead of MPG.
391 gears Fairbanks converter, and a 484 purple shaft that proberly was close to 240 degrees @ 50 duration.
And bought blemishes tires from a guy since I did burnouts like on Roadkill.
The good old days
