Original Ford 427 carburetor - Lemans bowels

Holley lists # 3255-1 as original equipment for a 1965-67 Ford 427 Hi-Riser race engine, 780 cfm, model 4150-C,
Ford # C5AF-9510BV, tag # C5AF-BVA. I believe this to be the original equipment carburetor for a 427 comp cobra.

Chassis Dyno - Last Run 427 High Riser

Self built 427 SO, stock stroke, 429 ci., Dove aluminum High Riser heads, mildly ported, 10.5 : 1 CR, original holley 780 cfm LeMans carb, vacuum secondary, on an original single four BBL , dual plane, Hi-Riser intake. Chassis Dyno is at Performance Engineering, Hamilton, OH.


Carb jets changed, and timing adjusted by Performance Engineering. Picked up 80 ft-lbs torque and 60 hp by chassis dyno tuning.


With a 20% loss, estimated max flywheel torque is about 600, with about 570 flywheel HP at 5900 rpm's and still climbing.


The torque curve is pretty flat.
