Match Race = 1968 Road Runner '383' vs. 1964 Belvedere '426-S' Street Wedge
First Hand Experience,
The 1964 Belvedere '426' Commando {Shipping Weight; #3347 lbs.}
Though the '426-S' {365 HP} was over-rated in the HP Department by the Factory, on the street it was consistently good.
* 365 HP @ 4800 RPM's
* 470 Ft/Lbs. of Torque @ 3200 RPM's
And, the 'Sedan' body style was 'stiff-and-rigid'.
Just add Gears and Headers, and the 426 Street Wedge was a top runner on the street.
Street Sleeper.
The only 'moniker' was the 426 Hood Emblem.
