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.

Installation of hoop portion of rollbar.

In process of rollbar installation. Bar was custom bent to 60's CSX specifications by Mickmate. Once the fishmouth is welded the tail portion of bar will be added. All bolt points are to frame making it functional via 0.120" wall tubing. Almost ready for paint and grommets.
