CLASS RACER FORUM - View Single Post - 1964 426-S 'Street-Wedge'

The 365 Horsepower rating was a 'tad' overblown,,,,,,,
Currently the NHRA rates them at 300 HP. More in line...

Evidently, the Carter #3611 AFB carburetor was under-sized
(same carburetor used on the 383 engines).
The AFB was rated at 575 CFM,,,,,,to go along with a poor flowing
low-riser cast iron intake manifold.

Even the 9.17 wt/hp for the light 64' Belvedere (#3347 lbs.) put it at the wrong end of the 8.70 - 9.49 wt/hp (1964 A/S) class break.

In 1964, in A/S, they were really no threat to the;
,,,64' GTO 389/348 HP 'Tri-Power' 4-speeds
,,,64' Impala SS 409/380 HP 4-speeds
,,,64' Galaxie 500 427/410 HP 4-speeds

Their 'best bet',,,,,was in A/SA (automatics), with the famous 'push-button' controls.
