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.

Ford_Raditor_Heat_Rejection_Chart- Street Rod Example
This chart compares the heat rejection rate (cooling capacity) of three different types of radiators tested on an old Ford Street Rod. Coolant flow rate is held constant at 7 gpm (typical flow at idle perhaps, not sure where its being measured ???). It graphs the heat rejection for each radiator versus air flow through the radiator core. It is comparing 3 diff rad designs/materials at different CFMs through the core. The more air flow you have for a given coolant flow rate (7 gpm in this example) , the higher the heat rejection, basically linear in this example. The author of this graph is most likely selling the high efficiency radiator showing the improvement over the other two designs. To sum it up, the radiator at the top of the chart appears to be the most efficient at a low coolant flow rate (7 gal/min) over all air flows tested. Ya see how important rad core/tank design is? I learned something here.
